Design a synthesis of 2-ethoxy-2-methylpropane from 2-methylpropene. q1 Part 1: Choose the best option for the immediate precursor to the target molecule. p1 p1c p1d4 p1d3 p1d2 6412p1a SN1 solvolysis of the tertiary bromide with the appropriate alcohol will produce the target molecule. Part 2 out of 6 Choose the best option for the precursor needed to make the alkyl bromide. p2 p2d3 p2d2 p2d1 p2c p2d4

The correct answer would be b) volume versus temperature, because they are also directly proportional.

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b
