Test: Characteristics of Halo Compounds - Question 3

In SN2 reactions, the correct order of reactivity for the following compounds: CH3Cl, CH3CH2Cl, (CH3)2CHCl and (CH3)3CCl is

Detailed Solution for Test: Characteristics of Halo Compounds - Question 3

Reactivity in SN2 is inversely proportional to steric hindrance.

Hence the correct order of reactivity is CH3Cl > CH3CH2Cl > (CH3)2CHCl > (CH3)3CCl

Hence, Option (c) is the answer.

Test: Characteristics of Halo Compounds - Question 4

Elimination of bromine from 2-bromobutane results in the formation of

Detailed Solution for Test: Characteristics of Halo Compounds - Question 4

2-bromobutane → CH3CH = CHCH3 + CH3CH2CH=CH2

The major product follows Saytzeff rule.

Hence option (A) is the correct answer.

Test: Characteristics of Halo Compounds - Question 5

Which of the following is a tertiary halogenoalkanes?

Detailed Solution for Test: Characteristics of Halo Compounds - Question 5

√Br CH3 -( CH )- CH2 - CH2 - CH3 √CH3 The carbon with which the Br is bonded is bonded with another 3 carbon atoms. So haloalkane is 3.

Test: Characteristics of Halo Compounds - Question 6

 Which of the following is not true about optical isomers?

Detailed Solution for Test: Characteristics of Halo Compounds - Question 6

Superimposable (mirror images of each other) substances are achiral because chiral substances cannot have its own mirror image. And achiral substances do not show optical activity nor any optical isomers. Hence, answer is B.

Test: Characteristics of Halo Compounds - Question 7

 Which of the following is not an aryl halide?

Detailed Solution for Test: Characteristics of Halo Compounds - Question 7

 Because it is Open chain compound /Aliphatic Compound and not aryl halide as it does not contain halogen atom. It's simply  alkane.

Test: Characteristics of Halo Compounds - Question 8

Pick up the correct statement about alkyl halides.

Detailed Solution for Test: Characteristics of Halo Compounds - Question 8

In general organic compounds are soluble in organic solvents. Hence alkyl halides are soluble in organic solvents.

Test: Characteristics of Halo Compounds - Question 9

 Which one of the following is 1-bromo-3-methyl butane?

Detailed Solution for Test: Characteristics of Halo Compounds - Question 9

It is 1-bromo-3-methylbutane.

Test: Characteristics of Halo Compounds - Question 10

C5H11Br is least soluble in:

Detailed Solution for Test: Characteristics of Halo Compounds - Question 10

C5H11Br are only very slightly soluble in water. They are more soluble in organic solvents.
