The isomer is
1 Dextro isomer
2 Laevo isomer
3 Cis isomer
4 Trans- isomer
Explanation:
(D) : In the complex B-M-B are trans to each other then the isomer is called trans isomer.

Consider the following structures : Which One of the following is correct in respect of above structures?
1 Anomers
2 Epimers
3 Enantiomers
4 Aldopentose
Explanation:
**Epimers :** Either of two stereoisomers that differ in the arrangment of groups on a single asymmetric carbon atom such as the first chiral center of suger's carbon chain. The given structure are not non-super-imposable mirror images. So, these are not enantiomers. Hence, it is epimers.

Consider the following compound : Which of the carbon atoms in this compound is/are asymmetric?
1 $\mathrm{C}-1$ and $\mathrm{C}-4$
2 C-2 only
3 C-3 only
4 C-2 and C-3
Explanation:
Asymmetric carbon have four different group. Thus carbon-2 only asymmetric i.e. chiral.
