Write the condensed structural formulas for the following alcohols."" Correct the incorrect names.""
4-methyl-1-pentanol
2-methyl-2-butanol
3-ethyl-1-butanol
2, 2-diethyl-4-pentanol
3-ethyl -2-hexanol
IS THERE ANY WRONG NAMES??
Take a look at 3 and 4. 3 appears to be a pentanol to me. 4 appears to be a hexanol to me. Check it out.
How
The ethyl group on both 3 and 4 make the chain one C longer. I can't draw it on this forum but try google the names you have and see how they look then count the longest C chain.
To write the condensed structural formulas for the given alcohols and correct any incorrect names, we need to follow a systematic approach:
1. 4-methyl-1-pentanol:
Start by identifying the longest carbon chain, which is 5 carbons long in this case (pentanol). Since the name states a methyl group (CH3) is attached to the 4th carbon, we can place it accordingly. The correct name is 4-methylpentanol.
Condensed structural formula: CH3-CH2-CH2-CH(CH3)-CH2-OH
2. 2-methyl-2-butanol:
The longest carbon chain is 4 carbons long (butanol). Since the name indicates a methyl group (CH3) is attached to the 2nd carbon, we can place it accordingly. The correct name is 2-methylbutanol.
Condensed structural formula: CH3-CH(CH3)-CH2-CH2-OH
3. 3-ethyl-1-butanol:
Once again, identify the longest carbon chain, which is 4 carbons long (butanol). As the name suggests, an ethyl group (C2H5) is attached to the 3rd carbon. The correct name is 3-ethylbutanol.
Condensed structural formula: CH3-CH2-CH(CH2CH3)-OH
4. 2,2-diethyl-4-pentanol:
The longest carbon chain in this case is 5 carbons long (pentanol). With two ethyl groups (C2H5) attached to the 2nd carbon, we can properly name it 2,2-diethylpentanol.
Condensed structural formula: CH3-CH2-CH(C2H5)-CH(C2H5)-CH2-OH
5. 3-ethyl-2-hexanol:
Identify the longest carbon chain, which is 6 carbons long (hexanol). As the name indicates, an ethyl group (C2H5) is attached to the 3rd carbon. The correct name is 3-ethylhexanol.
Condensed structural formula: CH3-CH2-CH(CH2CH3)-CH2-CH2-CH2-OH
In the given list, all the names have been corrected and condensed structural formulas have been provided for each alcohol.
