Question 1
1 / -0

Which among the following is a geminal dihalide?

A
Ethylene dihalide

B
Ethylidene dihalide

C
Allyl chloride

D
Chloroethyne

Solution

1,1-dichloroethane (ethylidene dihalide) is a geminal dihalide.
Question 2
1 / -0

Vinyl chloride and propargyl chloride are respectively the chloro derivatives of

A
alkenes and alkynes

B
alkanes and alkenes

C
alkynes and alkenes

D
alkynes and alkanes

Solution

CH₂=CH–CI and CI–CH₂–C ≡ CH
(Vinyl chloride) (Propargyl chloride)
Question 3
1 / -0

Which among the following is an allyl halide?

A
Chlorobenzene

B
1–Chlorocyclohex-1-ene

C
Chloroethene

D
3-Chlorocyclohex-1-ene

Solution

All others are vinyl chlorides.
Question 4
1 / -0

The increasing order of boiling points in the following alkyl halides is

A
(CH₃)₃CCl < (CH₃)₂CHCH₂Cl < CH₃CH₂CHClCH₃ < CH₃CH₂CH₂Cl

B
(CH₃)₃CCl < CH₃CH₂CH₂Cl < CH₃CH₂CHClCH₃ < (CH₃)₂CHCH₂Cl

C
CH₃CH₂CHClCH₃< CH₃CH₂CH₂Cl < (CH₃)₃CCl < (CH₃)₂CHCH₂Cl

D
CH₃CH₂CHClCH₃< (CH₃)₂CHCH₂Cl < (CH₃)₃CCl < CH₃CH₂CH₂Cl

Solution

The branched isomer has a lower boiling point due to lesser surface area.
Question 5
1 / -0

Identify the incorrect statement.

A
For the same alkyl group, the density of alkyl halides increases down the group.

B
Bond strength of alkyl halides decreases as the size of the halogen increases.

C
The dipole moment of alkyl halides decreases as the electronegativity of the halogen atom decreases.

D
Alkyl halides are sparingly soluble in water.

Solution

Alkyl fluorides have a lower dipole moment than alkyl chlorides due to smaller bond length.
Question 6
1 / -0

Among the following alkyl halides, the one which is not an α, ω–dihalide is

A
ClCH₂CH₂Cl

B
ClCH₂CH₂CH₂Cl

C
ClCH₂CH₂CH₂CH₂Cl

D
(Cl)₂CHCH₃

Solution

In α, ω–dihalides, two halogen atoms are present on the two terminal carbon atoms.
Question 7
1 / -0

The IUPAC name of chloral (C₂HCl₃O) is

A
2,2-Trichloro eth-1-enol

B
2,2,2-Trichloroethanal

C
2,2-Dichloroethanoyl chloride

D
None of the above

Solution

2,2,2-Trichloroethanal is the IUPAC name of Cl₃CCOH.
Question 8
1 / -0

By the action of PCl₅on glycol, the product(s) obtained is/are:

A
ClCH₂-CH₂Cl

B
Cl₂CH-CH₃

C
POCl₃

D
Both (1) and (3)

Solution
