Most likely the organic compound that contains a carbonyl group bonded near to the end of the chain would be an aldehyde. Unlike a ketone where the carbonyl can be found anywhere within the chain, an aldehyde, is specifically found near the end of the compound, because it would be bonded to H as well.

Answer from: danielasena21

Answer : The correct option is, Aldehyde.

Explanation :

Ketone group : It is the class of organic compound in which the -CO group is attached to a hydrocarbon is known as ketone.

The general representation of ketone are, R-CO-R' .

For example : Acetone, H_3C-CO-CH_3

Aldehyde group : It is the class of organic compound in which the -CHO group is attached to a hydrocarbon is known as aldehyde.

The general representation of aldehyde are, R-CHO .

For example : Ethanal , H_3C-CH_2-CHO

Ether group : It is the class of organic compound in which the oxygen is directly attached to the two alkyl group of carbon is known as ether.

The general representation of ether are, R-O-R^' .

For example : Dimethyl ether, H_3C-O-CH_3

Amine group : It is the class of organic compound in which the -NH_2 group is directly attached to the alkyl group of carbon is known as amine.

The general representation of amine are, R-NH_2 .

For example : Ethylamine, H_3C-CH_2-NH_2

As per question, aldehyde is an example of an organic compound that contains an attached carbonyl group at the end of the carbon chain.

Hence, the correct option is, Aldehyde.

Answer from: Quest

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
