Question

complete the table by typing the name of the functional group found in each of the following organic compounds.
organic compound | functional group
h—c≡c—h |
oh
|o
||
|c—(ch₂)₂—ch₃
||
|o
|
ho—ch₃ |

Explanation:

To solve for the functional groups of each organic compound, we analyze each structure:

1. For $\boldsymbol{\ce{H - C\equiv C - H}}$

• The structure has a carbon - carbon triple bond ($\ce{C\equiv C}$).
• Compounds with a carbon - carbon triple bond are alkynes, and the functional group is an alkyne (or carbon - carbon triple bond).

2. For $\boldsymbol{\ce{OH - C(=O) - (CH_2)_2 - CH_3}}$

• The structure has a $\ce{-COOH}$ (carboxylic acid) group (since it has a carbonyl group $\ce{C=O}$ attached to a hydroxyl group $\ce{-OH}$ and an alkyl chain).
• The functional group here is a carboxylic acid (or carboxyl group, $\ce{-COOH}$).

3. For $\boldsymbol{\ce{HO - CH_3}}$ (methanol - like structure, $\ce{CH_3OH}$)

• The structure has a $\ce{-OH}$ group attached to a carbon atom (the carbon is part of a methyl group here).
• Compounds with a $\ce{-OH}$ group attached to a saturated carbon (not part of a carbonyl group) are alcohols, so the functional group is an alcohol (or hydroxyl group, $\ce{-OH}$).

Filling the Table (assuming a table with rows for each compound and column for functional group):

Organic compound	Functional group
$\ce{OH - C(=O) - (CH_2)_2 - CH_3}$	Carboxylic Acid (Carboxyl Group)
$\ce{HO - CH_3}$ (or $\ce{CH_3OH}$)	Alcohol (Hydroxyl Group)

If you need the answers in a more concise format (just the names of the functional groups for each compound in order):

1. Alkyne (or Carbon - Carbon Triple Bond)
2. Carboxylic Acid (or Carboxyl Group)
3. Alcohol (or Hydroxyl Group)
