Name the following groups:
| | |
| :---------- | :--------------- |
| [tex]$CH_3-$[/tex] | Amine |
| [tex]$CH_3CH_2CH_2CH_2CH_2-$[/tex] | Hydroxyl group |
| | Methyl group |
Answer (2)
C H 3 − is identified as a methyl group.
C H 3 C H 2 C H 2 C H 2 C H 2 − is identified as a pentyl group.
The methyl group is C H 3 − .
The pentyl group is C H 3 C H 2 C H 2 C H 2 C H 2 − .
C H 3 is methyl group, C H 3 C H 2 C H 2 C H 2 C H 2 is pentyl group
Explanation
Problem Analysis The problem asks us to identify two chemical groups, C H 3 − and C H 3 C H 2 C H 2 C H 2 C H 2 − , and to determine which of the provided options corresponds to the methyl group.
Identifying the First Group C H 3 − is a methyl group. It consists of one carbon atom and three hydrogen atoms.
Identifying the Second Group C H 3 C H 2 C H 2 C H 2 C H 2 − is a pentyl group. It is an alkyl group with five carbon atoms in a straight chain.
Identifying the Methyl Group Therefore, the methyl group is C H 3 − .
Examples
In organic chemistry, understanding functional groups like methyl and pentyl is crucial for predicting the properties and reactivity of molecules. For instance, methyl groups are often added to molecules to increase their hydrophobicity, while pentyl groups can contribute to the overall size and shape of a molecule, affecting its interactions with other molecules. Knowing these groups helps in designing new drugs or materials with specific properties.
The first group C H 3 − is a methyl group, while the second group C H 3 C H 2 C H 2 C H 2 C H 2 − is a pentyl group. Both of these groups are important in organic chemistry for understanding the structure and reactivity of compounds. Identifying and naming these groups is crucial for studying chemical interactions.
