Compound has which of the following prefix?
1 trans
2 Anti
3 $\mathrm{E}$
4 $\mathrm{Z}$
Explanation:
The given compound It groups or atom is having the same priority then it lies in opposite side. Therefore, compound will have 'E' prefix. is

GENERAL ORGANIC CHEMISTRY
232226 The above pair is known as
1 sructural isomers
2 geometrical isomers
3 erythro steroisomers
4 threo stereoisomers
Explanation:
The pair compound show Threo Isomer when two like Fischer projection are drawn and a same vertical line the isomer is called erthyro form. If these placed on opposite side then it is said to threo form

The structure shows
1 optical isomerism
2 geometrical and optical isomerism
3 tautomerism
4 geometrical isomerism
Explanation:
(B) : It has asymmetric carbon atom (marked $*)$ so it shows optical isomerism. Two groups attached to $\mathrm{C}=\mathrm{C}$ are same $\left(-\mathrm{CH}_{3}\right)$, so it does not show geometrical isomerism.
