Match the era on the left with its characteristic on the right.

Troyanec [42]

Answer:

Mesozoic - the era before the current one

Cenozoic - the current era

Paleozoic - when life first flourished

Precambrian - the first era

Explanation:

The Precambrian is the earliest part of Earth's history, the first era. It's named like this because it preceded the Cambrian - the first period of the Phanerozoic eon, which is the current geologic eon. It lasted from the beginning of Earth (about 4.6 billion years ago) to the beginning of the Cambrian Period (about 541 million years ago).

Paleozoic is an era that lasted from about 541 to about 252 million years ago. During this time, life began to flourish.

Mesozoic is an era that lasted from about 252 to 65 million years ago. It's the era that took place before the current one - the Cenozoic.

Carbonyl compounds can be protonated on the carbonyl oxygen. Protonation of the carbonyl oxygen gives a species whose positive c

zysi [14]

Answer:

Full explanation is given below.

Explanation:

Positive charge on carbonyl oxygen atom in protonated acetic acid is delocalized by stronger electron donating resonating effect of lone pair of oxygen atom in adjacent -OH group.

Positive charge on carbonyl oxygen atom in protonated acetone is delocalized by weaker electron donating inductive effect of two adjacent methyl groups.

Higher the delocalization of positive charge, higher will be stability of protonated species. Hence acetic acid is more rapidly protonated.

Resonance structures of protonated acetic acid has been shown below.
