It seems like there might be a typo in your question. If you are asking for a homologous series containing the functional group -CO (carbonyl group) and alkyne up to the first four members, it would typically involve compounds belonging to the carboxylic acid and alkyne functional groups.
Let's consider carboxylic acids with the general formula \( \text{RCOOH} \) and alkynes with the general formula \( \text{C}_n\text{H}_{2n-2} \).
Now, if you are looking for a series that combines both functional groups, you might consider compounds that contain both a carboxylic acid group and an alkyne group. However, such compounds are less common and may not follow a straightforward homologous series due to the complexity of the molecules.
If you have a different interpretation of "graup -CO,"
A homologous series involves a group of compounds that have similar structures and properties, differing only by the number of repeating units in their structures. For a series containing the functional group -CO (carbonyl group) and alkyne, we can consider the following homologous series:
Alkynones Series:
1. Methynone:
- Chemical Formula:
[tex]( CH_3CO \equiv CH) [/tex]
2. Ethinone:
- Chemical Formula:
[tex]( CH_3COC \equiv CH )[/tex]
3. Propynone:
- Chemical Formula:
[tex]( CH_3CO \equiv CCH_2) [/tex]
4. Butynone:
- Chemical Formula:
[tex]( CH_3COC \equiv CCH_2)[/tex]
In this series, each member has a carbonyl group (-CO) and an alkyne group. The alkynones are named based on the alkyl chain length and the presence of the carbonyl and alkyne functional groups. The first four members are listed above.

Answer:
It seems like there might be a typo in your question. If you are asking for a homologous series containing the functional group -CO (carbonyl group) and alkyne up to the first four members, it would typically involve compounds belonging to the carboxylic acid and alkyne functional groups.
Let's consider carboxylic acids with the general formula \( \text{RCOOH} \) and alkynes with the general formula \( \text{C}_n\text{H}_{2n-2} \).
1. **Carboxylic Acids (with -CO functional group):**
- Methanoic Acid: \( \text{HCOOH} \) (Formic Acid)
- Ethanoic Acid: \( \text{CH}_3\text{COOH} \) (Acetic Acid)
- Propanoic Acid: \( \text{C}_2\text{H}_5\text{COOH} \)
- Butanoic Acid: \( \text{C}_3\text{H}_7\text{COOH} \)
2. **Alkynes:**
- Ethyne: \( \text{C}_2\text{H}_2 \) (Acetylene)
- Propyne: \( \text{C}_3\text{H}_4 \)
- Butyne: \( \text{C}_4\text{H}_6 \)
- Pentyne: \( \text{C}_5\text{H}_8 \)
Now, if you are looking for a series that combines both functional groups, you might consider compounds that contain both a carboxylic acid group and an alkyne group. However, such compounds are less common and may not follow a straightforward homologous series due to the complexity of the molecules.

Alkynones Series:
1. Methynone:
- Chemical Formula:
[tex]( CH_3CO \equiv CH) [/tex]
2. Ethinone:
- Chemical Formula:
[tex]( CH_3COC \equiv CH )[/tex]
3. Propynone:
- Chemical Formula:
[tex]( CH_3CO \equiv CCH_2) [/tex]
4. Butynone:
- Chemical Formula:
[tex]( CH_3COC \equiv CCH_2)[/tex]
In this series, each member has a carbonyl group (-CO) and an alkyne group. The alkynones are named based on the alkyl chain length and the presence of the carbonyl and alkyne functional groups. The first four members are listed above.
