MCQ
Given below are two statements :
Statement I : Dimethyl ether is completely soluble in water. However, diethyl ether is soluble in water to a very small extent.
Statement II : Sodium metal can be used to dry diethyl ether and not ethyl alcohol.
In the light of given statements, choose the correct answer from the options given below
  • A
    Statement I is false but Statement II are true
  • B
    Both Statement I and Statement II are false
  • C

  • D
    Both Statement I and Statement II are true
✓

Answer

D. Both Statement I and Statement II are true
St-I : - St-I is correct because both given ether are soluble in water $\rightarrow$ Di ethyl ether and butan-1-ol are miscible to almost same extent i.e., 7.5 and 9 gm per 100 ml water due to H -bonding
St-II : - St. II is also correct because sodium metal is not used with ethyl alcohol as $\mathrm{H}_{2}$ gas release with ethyl a below
