Question 1
1 / -0

The compounds CH₃OC₃H₇ and C₂H₅OC₂H₅ exhibit

A
optical isomerism

B
cis-trans isomerism

C
metamerism

D
chain isomerism

Solution

The compounds having the same molecular formula, but different number of carbon atoms (or alkyl groups) on either side of the functional group, are called metamers and this phenomenon is called metamerism. Metamerism is exhibited by the compounds having a bifunctional group, i.e. -O-, -S-, -NH-, -CO-, etc.
Question 2
1 / -0

Which of the following is not true regarding electromeric effect?

A
It results in the appearance of partial charges on the carbon atom.

B
It is a temporary effect.

C
It operates on multiple bonds.

D
It requires an attacking reagent.

Solution

Electromeric effect is a temporary effect which takes place between two atoms joined by multiple bonds. This occurs at the requirements of the attacking reagent and involves instantaneous transfer of a shared pair of electrons of the multiple bond to one of the linked atoms.
