QUESTION: 1

Which of the following statements are correct in case of the carbonyl bond between carbon and oxygen?

Solution:

In carbonyl bonds b/w O and C, C is electrophilic centre(centre which needs electron as it is deficient in it) and O is nucleophilic centre(centre which needs +ve charge as it has excess charge).  Also, C=O bond is polarised with O having partial negative charge and C having partial positive charge.

QUESTION: 2

How many structural isomers can compound with molecular formula ‘C3H6O’ have?

Solution:

QUESTION: 3

What is the common name of 2-methyl-propanal?

Solution:

Isobutyraldehyde is the chemical compound with the formula (CH₃)₂CHCHO. It is an aldehyde, isomeric with n-butyraldehyde. Isobutyraldehyde is manufactured, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw.

QUESTION: 4

Write the IUPAC name of (CH3)2CHCHO?

Solution:

The IUPAC name of (CH3)2CHCHO is 2-methylpropanal and its chemical name is Isobutyraldehyde.

QUESTION: 5

Carbonyl compounds when oxidized easily to form carboxylic group involves

Solution:

AlcoholWhat Is the OH Functional Group Called? is the group in which (carbonyl) group is not present. Aldehydes, ketones and carboxylic acids all have a carbonyl group present in them. Aldehydes have group, ketones have a group and carboxylic acids have a group.

Hence A is correct.

QUESTION: 6

 Acetone is isomeric to:

Solution:

Aldehyde and ketone shows functional group isomerism .

QUESTION: 7

The IUPAC name of CH3CHO is:

Solution:
QUESTION: 8

What is the IUPAC name of Acrolein?

Solution:
QUESTION: 9

 Which of the following statement about C=O and C=C is correct?

Solution:

The first bond formed is a sigma bind and the second one is a pi bond.
O has a higher electronegativity than C and hence the electron cloud will be shifted towards the O atom, making the compound polar. This is not possible in C=C.

QUESTION: 10

Propanone and prop-2-en-1-ol are examples of which type of isomerism?

Solution:

The correct answer is Option A

Propanone (a ketone) and,
Prop-2-en-1-ol with molecular formula C3H6O (an aldehyde) exhibit functional isomerism.

Functional isomerism, an example of structural isomerism, occurs when substances have the same molecular formula but different functional groups. This means that functional isomers belong to different homologous series.

Hence, Option A is correct.
