Write the name and draw full structural formula of (CH3)3COH, and (CH3)2CH(OH)
The correct answer and explanation is:
Sure! Here are the names and full structural formulas for the given compounds:
1. (CH3)3COH
Name: tert-Butanol or 2-methyl-2-propanol
Structural Formula:
OH
|
CH3-C-CH3
|
CH3
Explanation of structure:
- The central carbon (C) is bonded to three methyl groups (CH3) and one hydroxyl group (OH).
- This makes it a tertiary alcohol because the carbon bearing the OH group is attached to three other carbons.
2. (CH3)2CH(OH)
Name: Isopropanol or 2-propanol
Structural Formula:
OH
|
CH3 - CH - CH3
Explanation of structure:
- The central carbon is bonded to one hydroxyl group (OH), one hydrogen (not shown explicitly), and two methyl groups (CH3).
- This is a secondary alcohol because the carbon with the OH is attached to two other carbons.
Explanation (about the formulas and naming):
The formulas given are condensed formulas for alcohols. Alcohols are organic compounds that contain a hydroxyl group (-OH) attached to a carbon atom. The position and substitution pattern around the carbon with the OH determine the classification and naming of the alcohol.
- (CH3)3COH corresponds to a tertiary alcohol because the carbon attached to the hydroxyl is connected to three other carbons. This particular alcohol is called tert-butanol, where “tert-” refers to the tertiary nature of the carbon bearing the OH group. Its IUPAC name is 2-methyl-2-propanol, indicating that the OH is on the second carbon of a propane chain with a methyl substituent also on the second carbon.
- (CH3)2CH(OH) corresponds to a secondary alcohol, with the OH-bearing carbon attached to two other carbons. This is isopropanol, commonly used as rubbing alcohol. The IUPAC name is 2-propanol, indicating the OH group is on the second carbon of propane.
The structural formulas clearly show the arrangement of atoms in space, which is important for understanding the chemical properties and reactivity of these alcohols. Tertiary alcohols like tert-butanol tend to be more sterically hindered and have different reactivity compared to secondary alcohols like isopropanol.
