Question 3: option D is correct
Explanation: NaBH4 is a reducing agent which reduces aldehyde to primary alcohol.
Question 10: option A is correct
Explanation: The structure having less number of carbon atoms has least boiling point and the structure having more number of carbon atoms has highest boiling point due to increase in vanderwaal forces of attractions.
Question 13: option C is correct
Explanation: The number of carbon atoms in the longest carbon chain are 6 so the rootword is hex-. A methyl group is located at 5th position and the functional group is ketone so the name is 5-methyl-3-hexanone.
