Question

Which of the following reactions could be used to synthesize tort-butylbenzene? a. C_6 H_6 + CH_2(C(CH_3)_2 b. C_6 H_6 + (CH_3) COH c. C_6 H_6 + (CH_3)_3 CCI d. All of these Which of the following compounds would be most reactive toward electrophilic substitution? a. I b. II c. III d. IV e. V Which reagent (s) would you use to carry out the following transformation? ethylbenzene rightarrow 1-chloro-1-phenylethane a. Cl_2, light, and heat b. Cl_2, FeCl_3 c. SOCI_2 d. C_2H_5Cl, AlCl_3 e. HCl, O_2 LiAlH_4 (LAH) cannot be used to convert carboxylic acids to the corresponding aldehydes because: a. LAH is not sufficiently reactive. b. RCOOH is converted into RCOOLi. c. RCOOH is reduced to RCH_2OH. d. RCOOH is reduced to RCH_3. e. RCOOH is converted into RCR.

Explanation / Answer

7) option D is correct

8) option A is correct (-OH group is a strong electron donating group which increases the electron density on benzene ring so it is more reactive towards electrophilic aromatic substitution reaction.)

9) option A is correct (Cl2 in presenc of light gives chlorination at benzylic position.)

10) option C is correct (LiAlH4 is a strong reducing agent which reduces carboxylic acid to alcohol.)
