From Acid to Alcohol and Back — Reduce
Acid -> 1 alcohol (named strong hydride). Aldehyde is the halfway if you could stop (hard). Nitrile + LiAlH4 -> amine named in the next chapter if linked. Ester link: acid + alcohol reversible; hydrolysis returns acid and alcohol. This page separates the idea from the wider topic “FROM ACID TO ALCOHOL AND BACK” so it can be revised and assessed on its own.

What is it?
Acid -> 1 alcohol (named strong hydride). Aldehyde is the halfway if you could stop (hard). Nitrile + LiAlH4 -> amine named in the next chapter if linked. Ester link: acid + alcohol reversible; hydrolysis returns acid and alcohol. This page separates the idea from the wider topic “FROM ACID TO ALCOHOL AND BACK” so it can be revised and assessed on its own.
In simple words
- Acid -> 1 alcohol (named strong hydride).
- Ethanoic -> ethanol
- Exam link: strong reductant name.
Important terms
REDUCE: Acid -> 1 alcohol (named strong hydride).
FROM ACID TO ALCOHOL AND BACK: Reduction of carboxylic acids is harder than of aldehydes (LiAlH4 named if the book has it; NaBH4 often not enough).
What you should learn
- Define reduce using accurate chemistry terms.
- Explain why reduce matters within from acid to alcohol and back.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Examples
- Ethanoic -> ethanol
- LiAlH4 named
- Not a SOP

WHY — Why this topic matters
FROM ACID TO ALCOHOL AND BACK — REDUCE is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
Acid -> 1 alcohol (named strong hydride). Aldehyde is the halfway if you could stop (hard). Nitrile + LiAlH4 -> amine named in the next chapter if linked. Ester link: acid + alcohol reversible; hydrolysis returns acid and alcohol. Examples: Ethanoic -> ethanol; LiAlH4 named; Not a SOP. Exam use: Exam hill: 1 alcohol -> aldehyde -> acid (ox) acid back to 1 alcohol needs a named strong reductant ketones do not become acids with Tollens
