Question

Which of these would be the rate law for an S_N 1 reaction? a) rate = k [RX] b) rate = k [RX] [Nucleophile] c) rate = k [RX]^2 d) rate = k [Nucleophile]^2 For Problems 13 and 14, consider this reaction: CH_3 CH_2 CH_2 Br + NaSH rightarrow CH_3 CH_2 CH_2 SH + NaBr What effect does doubling the concentration of NaSH have? a) doubles the rate b) halves the rate c) quadruples the rate d) has no effect on the rate What effect does doubling the concentration CH_3 CH_2 CH_2 Br have? a) doubles the rate b) halves the rate c) quadruples the rate d) has no effect on the rate In the term "E_2". what does the E stand for and what does the 2 stand for? Why does this reaction not give the indicated product? Looking at the mass spectrum, how could you tell whether you had CH_3 Br or C_2 H_10? What would you see in the spectrum for CH_3 Br, and what would you see in the spectrum of C_7 H_10?

Explanation / Answer

Ans 12 . a) rate = k [RX]

Sn1 reaction is unimolecular nucleophilic substitution reaction which depends upon the concentration of only alkyl halide.

The reaction is first order reaction , which occurs in 2 steps.

Carbocation is formed in the first step , which is then attacked by the nucleophile to form the products .
