Question 1
1 / -0

Assertion: Addition reaction of water to but-1-ene in acidic medium yields butan-1-ol.

Reason : Addition of water in acidic medium proceeds through the formation of primary carbocation.

A
Assertion and reason both are correct and reason is correct explanation of assertion.

B
Assertion and reason both are wrong statements.

C
Assertion is correct statement but reason is wrong statement.

D
Assertion is wrong statement but reason is correct statement.

Solution

Addition reaction of water to but-1-ene in acidic medium yields butan-2- ol.

Addition of water in acidic medium proceeds through the formation of a secondary carbocation.
Question 2
1 / -0

Assertion: p-nitrophenol is more acidic than phenol.

Reason: Nitro group helps in the stabilisation of the phenoxide ion by dispersal of negative charge due to resonance.

A
Assertion and reason both are correct and reason is correct explanation of assertion.

B
Assertion and reason both are wrong statements.

C
Assertion is correct statement but reason is wrong statement.

D
Assertion is wrong statement but reason is correct statement.

Solution

P-nitro phenol is more acidic as nitro group helps in the stabilization of the phenoxide ion by dispersal of negative charge due to resonance.
Question 3
1 / -0

Assertion : Boiling points of alcohols and ethers are high.

Reason : They can form intermolecular hydrogen-bonding.

A
Assertion and reason both are correct and reason is correct explanation of assertion.

B
Assertion and reason both are wrong statements.

C
Assertion is correct statement but reason is wrong statement.

D
Assertion is wrong statement but reason is correct statement.

Solution

Boiling points of alcohols are higher than that of ethers of comparable molecular mass.

Alcohols can form intermolecular hydrogen bonding while ethers cannot.
