Which of the following is an organometallic compound ?
- CH3COONa
- CH3CH2MgBr
- (CH3COO)2Ca
- CH3ONa
The Correct Option is B
Approach Solution - 1
An organometallic compound is a compound that contains a bond between a carbon atom of an organic molecule and a metal (usually a transition metal or main group metal).
Let's review the options:
- Option 1: CH₃COONa - This is sodium acetate, which is an ionic compound and does not contain a carbon-metal bond. Hence, this is not an organometallic compound.
- Option 2: CH₃CH₂MgBr - This is ethylmagnesium bromide, an organometallic compound. It contains a carbon-magnesium bond (C-Mg), which is a characteristic feature of organometallic compounds. Therefore, this is the correct answer.
- Option 3: (CH₃COO)₂Ca - This is calcium acetate, which is an ionic compound and does not have a carbon-metal bond. Therefore, this is not an organometallic compound.
- Option 4: CH₃ONa - This is sodium methoxide, an ionic compound that does not contain a carbon-metal bond. Hence, this is not an organometallic compound.
Conclusion: The correct answer is Option 2: CH₃CH₂MgBr, as it is an organometallic compound due to the carbon-magnesium bond.
Approach Solution -2
An organometallic compound contains at least one bond between a carbon atom and a metal atom.
- \(\text{CH}_3\text{COONa}\) is a sodium salt of acetic acid, which is not an organometallic compound.
- \(\text{CH}_3\text{CH}_2\text{MgBr}\) is a Grignard reagent, which is a classic example of an organometallic compound. It contains a bond between carbon and magnesium.
- \((\text{CH}_3\text{COO})_2\text{Ca}\) is calcium acetate, which is not an organometallic compound.
- \(\text{CH}_3\text{ONa}\) is sodium methoxide, which is not an organometallic compound as it doesn't contain a metal-carbon bond.
Thus, the correct answer is \(\text{CH}_3\text{CH}_2\text{MgBr}\).
