8) answer (c) 3,2,1=4
reason : 3 is tertiary carbocation so more stable , 2 is secondary carbocation and 1,4 are primary carbocation
carbocation stability = 30 > 20 > 10
9) answer : (v) all the above

QUESTION 24 Rank the following carbocations in order of stability. (The most stable is first.) T> III > 1 all > > II T>ll> 111 ll>I> III
1. Rank the following carbocations in order of increasing stability. “1” is the least stable, “4” is the most stable. (2 pts) CH3 2. Predict the major organic products formed in the following reactions. Be certain to indicate stereochemistry in your products if it is important. (12 pts) H2 Pd/C НСІ.
east stable most stable The following are three examples of the relative stability of carbocations in your answer to question 2. Each of these reactions should show a relatively stable carbocation intermediate. (a) The two-step reaction of 1-methylcyclohexene with HBr follows the Markovnikov 3. rule. (b) Choose 1-butanol or tert-butyl alcohol to undergo a 3-step reaction with HBr to form the alkyl bromide. The second step is the S1 formation of a carbocation. (c) Show the one most stable resonance...
