Racemic compound has
1 equimolar mixture of enantiomers
2 1:1 mixture of enatiomer and diastereomer
3 1:1 mixture of diastereomers
4 1:2 mixture of enantiomers
Explanation:
An equimolar mixture of the enantiomers (dextro or laevo froms) is called racemic mixture. It is represented as dl-form or \pm form and is optically inactive due to external compensation separation of racemic mixture into d- and l- forms is called resolution. Example :

1 chain isomerism
2 functional isomerism
3 position isomerism
4 metamerism
Explanation:
and are the example of functional group isomer in which group attached in ethanol while -o- group is attached in ether.

Which one of the following will show optical isomerism
1
2
3
4
Explanation:
Compound to optical isomer is it must have at least one Asymmetric center. Asymmetric center, a center which an atom (carbon) is hybridised and attached to 4 different substituent. Compound does not show optical isomer due to obsence of chiral center or Asymmetric center

Explanation:
Tautomerism-Tautomer are isomer of a compound which differ only in the position of electron and proton. The carbon skelton of a compound does not change.
