Question 12 :
Which of the following compounds will give ethyl alcohol on reduction with $LiAIH_{4}$?
Question 13 :
Statement-1: In the fermentation process of molasses, along with yeast, $(NH_{4})_{2}SO_{4}$ and $(NH_{4})_{3}PO_{4}$ are added.<br/>Statement-2: Both $(NH_{4})_{3}PO_{4}$ and $(NH_{4})_{2}SO_{4}$ act as food and help in the growth of yeast.<br/>
Question 14 :
Assertion: Solubility on n-alcohols in water decreases with increase in molecular weight.<br/>
Reason: The relative proportion of the hydrocarbon part in alcohols increases with increasing molecular weight which permits enhanced hydrogen bond with water.
