Uracil is one of the bases in RNA, a close relative of DNA.

(a) What are the values of the O—C—N and C—N—H angles?
(b) There are two carbon–carbon bonds in the molecule. Which is predicted to be shorter?
(c) If a proton (H⁺) attacks the molecule, decide on the basis of the electrostatic potential surface to which atom or atoms it could be attached.
