(a)
Interpretation: The chemical formula of the given compound should be determined.
Concept Introduction: Binary acids are named by using the prefix ‘hydro-‘followed by the base name of the anion and then the suffix ‘-ic’ is used. In the case of oxoacids, the base name of oxoanion has the suffix ‘-ous’ or ‘-ic.

Answer to Problem 75A
The chemical formula of nitrous acid is
Explanation of Solution
Nitrous acid contains hydrogen ions and nitrite ions. If the anion name of an acid containing oxygen ends in ‘-ite’ then the name of the acid ends in ‘-ous’. So, in nitrous acid, the anion is a nitrite ion, hence the name

- 1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
