Which of the following statements about organic reaction mechanisms is/are correct? (A) In acidic medium, an alcohol R-OH gets protonated to form R-OH2+. (B) Monochlorination of 2-methylbutane with Cl2 under UV light gives exactly two monochloro products in the ratio 33.3%: 66.6%. (C) Elimination reactions are favoured at high temperatures over substitution reactions. (D) Triphenylchloromethane (Ph3CCl) undergoes rapid hydrolysis via the SN1 mechanism.
- A, B and C only
- A, C and D only
- B, C and D only
- A, B, C and D
Correct answer: A, C and D only
Solution
Statements A, C, and D are correct. Statement B is wrong because 2-methylbutane has four distinct sets of hydrogen atoms, so monochlorination can give four different monochloro products, not just two.
