Organic reactions:

You must write the complete reaction by chemical formulas like the given example.

Example: CH3-CH=CH2 + H2O --> CH3-CHOH-CH3

1) 3-methyl pentene + H2O -->

2) 3-bromo butanan-2-ol + IOI -->

3) ethy 2- iodo butanoate + H2O --> (hydrolysis)

4) ethanol + 2- bromo- 3-methyl butanoic acid -->
