1 Chapter 10 OWL practice questions_Answers Q1. Draw a structural formula for the following compounds a. 1-chloro-1-methylcyclohexane . ANS : b. 3-ethyl-1-iodopentane . ANS : c. 3-bromo-2-chloro-2-methylbutane . ANS : d. 1-bromo-4,4-dichloro-1-isopropylcycloheptane . ANS: Q2. The compound below is treated with chlorine in the presence of light. Draw the structure for the (organic) species produced by reaction of the compound with a chlorine atom. Assume reaction occurs at the weakest C- H bond. For examples in which the radical is a resonance hybrid, draw the most stable resonance form. a. ANS: Feedback: The weakest C-H bond is that which, upon breaking, generates the most stable radical. For simple alkyl radicals, the order of stability is tertiary > secondary > primary. Allylic and benzylic systems have increased stability. b. ANS:

2 c. ANS: d. ANS: Q3. In radical chlorination of alkanes, non-equivalent hydrogens react with chlorine atoms at different rates. At 35 o C, primary, secondary, and tertiary C-H bonds react at relative rates of 1 : 3.9 : 5.2 respectively. These are conditions of kinetic control where product ratios are determined by relative rates of formation. For example, if A is formed twice as fast as B, the A:B product ratio will be 2. Consider chlorination of the alkane below at 35 o C. a. 1) Specify the most reactive C-H bond(s), a-c . b 2) Specify the site of chlorination in the major monochloro substitution product, a-c . a b. 1) Specify the most reactive C-H bond(s), a-c . b 2) Specify the site of chlorination in the major monochloro substitution product, a-c . b c. 1) Specify the most reactive C-H bond(s), a-c . a 2) Specify the site of chlorination in the major monochloro substitution product, a-c . b d. 1) Specify the most reactive C-H bond(s), a-c . b 2) Specify the site of chlorination in the major monochloro substitution product, a-c . c
