232122 Compounds with $C_{4} H_{11} N$ as molecular formula can exhibit

1 Position isomerism

2 Metamerism

3 Functional isomerism

4 All the three

Explanation:

The possible isomers of $C_{4} H_{11} N$ are as
original image
Thus, it shows all, position isomerism, metamerism and functional isomerism.

1

{CH}_{3} CH (OH) CH (Cl) C_{2} H_{5}

2

{CH}_{3} CH (OH) CH (OH) {CH}_{3}

3

C_{2} H_{5} CH (OH) CH (OH) {CH}_{3}

232186 In assigning R-S configuration, which among the following groups has highest priority?

1

- {SO}_{3} H

2

- COOH

3

- CHO

4

- C_{6} H_{5}

Explanation:

In this question priority order decided on the basis of
- Atomic Number
- Mass Number
In this groups sulpher atom has highest Atomic No. So priority will be high for ${SO}_{3} H$ .

232126 Which of the following acids does not exhibit optical isomerism?

1 Tartaric acid

2 Lactic acid

3 Maleic acid

4

α

-amino acids

Explanation:

Structure of these acids are
original image
All of these acids except maleic acid have at least one chiral carbon $(^{*})$ hence these are optically active but maleic acid is not.

232130 The structures of ${({CH}_{3})}_{3} CBr$ and ${CH}_{3} {[{CH}_{2}]}_{3} Br$ represent

1 Chain isomerism

2 Position isomerism

3 Chain as well as position isomerism

4 Functional isomerism

Explanation:

The structure of ${({CH}_{3})}_{3} CBr$ and ${CH}_{3} {({CH}_{2})}_{3}$ $Br$
original image
Position of functional group is change. So, it is also a position isomer.
Chain as well as position isomer is correct isomerism
