Consider the structures of the constitutional isomers, compound A and compound B. When treated with aqueous acid, compound A undergoes isomerization to give a cis stereoisomer. In contrast, compound B does not undergo isomerization when treated with the same conditions. That is compound B remains in the trans configuration. Explain the difference in reactivity between compound A and compound B

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
