Draw their products form from this reactions

Here are the products for the reactions:

a) $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{OH} \xrightarrow{\text{PCC}}$
This is the oxidation of a primary alcohol (butan-1-ol) using Pyridinium Chlorochromate (PCC), which is a mild oxidizing agent. PCC oxidizes primary alcohols to aldehydes.

• Product Structure: $\boxed{\text{CH}_3\text{CH}_2\text{CH}_2\text{CHO}}$
• Product Name: Butanal

b) $\text{CH}_3\text{COCH}_3 \xrightarrow{\text{NaBH}_4}$
This is the reduction of a ketone (propanone) using Sodium Borohydride ($\text{NaBH}_4$), a common reducing agent. Ketones are reduced to secondary alcohols.

• Product Structure: $\boxed{\text{CH}_3\text{CHOHCH}_3}$
• Product Name: Propan-2-ol
