Determine which base will work to deprotonate each compound in an acid/base extraction. Benzene ring with a carboxylic acid on one carbon and a methyl ester group on the opposite carbon
Benzene ring with a three carbon chain attached to one carbon. At the other end of the three carbon chain is a hydroxyl group.
Benzene ring with a hydroxyl group attached to one carbon and a tertbutyl group attached to the opposite carbon -

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
