This rule is simple, the nucleophile will add to the more substituted carbon. This leaves hydrogen to add to the less substituted carbon. Hence if we simply add sulphuric acid we can obtain Propan-2-ol from Propene. 2, 4, 6-trinitrophenol.

To convert propene to propan-1-ol, we will use the method of reaction of propene with peroxide. Complete step-by-step answer: Reaction of alkene with hydrogen halide in presence of peroxide results Anti Markovnikov’s addition.

Ethanol on oxidation with KMnO4 gives carboxylic acid. Carboxylic acid reaction with Ca(OH)2gives Ca+2. salts of carboxylic acid which on decarboxylation gives propane/ Acetone.

(1) Propanal: When propanal is hydrogenated at 413K in te presence of finely divided nickel, propan -1-ol isobtained. (2) Propanoic acid: When propanoic acid is reduced in the presence of LiAlH4 propan-1-ol is formed.

CHEBI:17153 – propanal Propionaldehyde or propanal is the organic compound with the formula CH3CH2CHO. It is the 3-carbon aldehyde. It is a colourless, flammable liquid with a slightly fruity odour. It is produced on a large scale industrially.

Solution

1. Methanal reacts with methyl magnesium iodide in presence of dry ether to give an addition compound, which on acid hydrolysis gives ethanol.
2. Ethanal reacts with methyl magnesium iodide in presence of dry ether to give an addition compound, complex which on acid hydrolysis gives propan-2-ol.

By treating the propanal with the K2Cr2O7, and H3O+, you will get the carboxy acid. Treat that acid with the SOCl2 to get the propanoyl chloride. Now, treat with ( CH3)2CuLi in the ether and reduce with the NaBH4 in the methanol to get the butan-2-ol as output.

Convert butan-2-one to butan-2-ol Alcohols can be prepared by oxidation of hydrocarbons and reduction of carbonyl compounds. Complete Answer: -Butan-2-ol is converted to butan-2-ol using lithium aluminum hydride which is LiAlH4 it is a reducing agent which is used to reduce ketones to alcohols.

To convert propanol to 2- butanol, first step would be to oxidise propanol to propanal (an aldehyde) assuming you are starting with 1-propanol. Also the choice of the oxidising agent is important.

Hence NaOH,I2/H+ can be used to convert 2-butanone into propanoic acid.

The steps used for conversion of acetaldehyde to 2-butanol are: Step 1 : Reaction of acetaldehyde with Grignard reagent. In Grignard reagent, the alkyl group behaves as a nucleophile and gets added to electrophilic carbon of aldehyde to give an addition product. Step 2 : Hydrolysis of addition product.

Zn-Hg/HCI.

As conversion increased, the selectivities of butanol and butene decreased, showing the formation of butane from butanone through a series reaction pathway: butanone → 2-butanol → butene → butane.

Step 1: Add NaBH4 to the mixture in an ethanolic solvent(on this case butanol is advised, other wise you will need to separate the two alcohols using fractional distillation). Step 2: Soak the mixture in cotton wool and place in a similar looking equipment.

Conversion of but-1-ene to but-2-ene is by catalytic isomerisation. But-1-ene undergoes isomerisation to but-2-ene on a nickel catalyst in the presence of hydrogen atoms.

Its main uses are in the production of gasoline (petrol) and butadiene, although some 2-butene is also used to produce the solvent butanone via hydration to 2-butanol followed by oxidation.

We know that greater are the number of alkyl groups attached to the doubly bonded carbon atoms, more stable is the alkene. Moreover, but-2-ene is a symmetrical molecule as compared to but-1-ene and therefore is more stable than the latter. …

To convert ethanol to but-1-yne: We have to convert a 2 carbon compound to a 4 carbon compound. First, convert the ethanol to bromoethane with hydrobromic acid and a little amount of H2SO4 Next, take acetylene and react with NaNH2 to form sodium acetylide. Now, add the bromoethane and acetylide to form but-1-yne.

When 2-chlorobutane is treated with solid sodium in the presence of dry ether, it results in the formation of 3,4-dimethylhexane.

Answer. When prop-1-ene is reacted with hydrogen bromide, the negative part goes to the carbon atom which has less number of hydrogen atoms. This rule is known as Markonikov’s rule. The conversion is given in the image below.

The conversion of benzene to chlorobenzene is as follows: Reduce it to Aniline by reacting Nitrobenzene with Sn+HCl or Fe+HCl or H2/Pd. Add NaNO2 +HCl to form benzene Dizonium chloride. React it with CuCl (Sandmeyer’s Rxn) or Cu Powder (Gatterman Rxn) to form Chlorobenzene.

– To convert benzene to biphenyl, we use the Wurtz Fittig reaction. First we convert the benzene ring to chlorobenzene using chlorine gas in the presence of anhydrous aluminium chloride through a chlorination reaction. Now we convert the chlorobenzene to biphenyl in presence of sodium in dry ether.

chloroethane can be converted into butane by simple wurt reaction which is a coupling reaction in which 2 moles of halo-alkane reacts with 2 moles of sodium in the presence of anhydrous ether(dry ether)to give n-alkane of higher order which must have even number of carbon atoms.

1. Start by reacting the ethane with an equivalent of chlorine, giving chloroethane CH3-CH2Cl.
2. Take half the chloroethane and react it with a strong (but not too nucleophilic) base to obtain ethene (ethylene, CH2=CH2).

Acetic acid is converted to Methane by the process of a reaction known as Oakwood Reaction. In this reaction decarboxylation of this acetic acid is performed to give a lower alkane. Ethanoic acid is first treated with Sodium Hydroxide to form Sodium Ethanoate.

To convert the chlorobenzene to 2-chloroacetophenone, it is made to react with a substance called acetyl chloride ( ) in the presence of anhydrous as catalyst. Due to Friedel craft acetylation reaction, it gets converted into 2-chloroacetophenone which is the expected product.

When aniline is treated with nitrous acid or sodium nitrite and HCl at chilled temperatures, it gets converted to a diazonium salt benzene diazonium chloride, which undergoes Sandmeyer’s reaction where treatment with CuBr gives Bromobenzene, or it can also undergo Gatterman’s reaction where the diazonium salt is …

Hint: Conversion of benzene to 4-bromonitrobenzene is a two-step process. Benzene converts to bromobenzene through a brominating catalyst. The brominated product is heated with mixed acid to get the required product.
