$\alpha-D(+)$ - glucose and $\beta-D(+)$-glucose are
1 enantiomers
2 geometrical isomers
3 epimers
4 anomers
Explanation:
Structure of $\alpha$-D Glucose and $\beta$-D Glucose Such pair of diasteromers which differ in configuration only around $\mathrm{C}_{1}$ are called anomers and $\mathrm{C}_{1}$ is called anomeric carbon or glycosidic carbon.

Optical isomerism is shown by
1 propanol-2
2 butanol-2
3 ethanol
4 methanol
Explanation:
(B): As we know that a-non symmetric carbon atom has a carbon atom attached to four different atom will show optical isomerism. So, 2-butanol is optically active, because chiral atom is present.

Geometrical isomers differ in
1 position of functional group
2 position of atoms
3 spatial arrangement of atoms
4 length of carbon chain
Explanation:
Geometrical isomer differ in Spatial arrangement of atoms. $\rightarrow$ This type of isomer arises due to difference in distance between groups around bond which about rotation is restricted

An aromatic compound has molecular formula $\mathrm{C}_{7} \mathrm{H}_{7} \mathrm{Br}$. Give the possible isomers and the appropriate method to distinguish them
1 3 isomers; by heating with $\mathrm{AgNO}_{3}$ solution
2 4 isomers; by treating with $\mathrm{AgNO}_{3}$ solution
3 4 isomers; by oxidation
4 5 isomers; by oxidation
Explanation:
From the given chemical formula of the question four isomers are possible. They can be separated by oxidation. Different isomer will give different products $-\mathrm{CH}_{3}$ will get oxidized to $-\mathrm{COOH}$.
