QUESTION 23 Which of the following statements are true? 1. ethanol is more soluble in water than dimethyl ether 2. ethanol has a higher boiling point than dimethyl ether 3. ethanol has the same molecular weight as dimethyl ether only 1 only 1 and 2 only 1 and 3 1, 2 and 3 QUESTION 24 In a unimolecular elimination (E1) reaction, the correct order of mechanistic steps is dissociation of the leaving group, then deprotonation at the position. simultaneous dissociation of the leaving group and deprotonation of the B position. association of the nucleophile/base, then dissociation of the leaving group. deprotonation at the B position, then dissociation of the leaving group. QUESTION 25 Which of the following is an accurate statement of Hammond's postulate? the transition state of an exothermic reaction will resemble the starting materials (reactants) more than the products the transition state of an exothermic reaction will resemble the products more than the starting materials (reactants) the transition state of an endothermic reaction will resemble the starting materials (reactants) more than the prochucts the difference in energy between the starting materials (reactants) and transition state controls the rate of a reaction MacBos

Answer 1

Vs. Question: 23 200 at ChoH CB-o-clb ethand dimethyl ether. 46 gmobi m.w: 46 & mott Ethanili more soluble than dimethyl ether due to mtor molecule H bonding. Ethand hon higher boiling point them demethyl ether due to intermolecules H-bonding M- wi .

Both of them have some molecular weight (46 gmoti) Home (1), (2) 4 (3) all of them are correct.
