Question

2) C → CH 4 → CH 3 Br → CH 3 OH → HCOH

Answer 1

Ответ:

Объяснение:

С +2H2 = CH4

CH4 + Br2 → CH3Br + HBr

CH3Br + H2O → CH3OH + HBr

CH3OH → HCOH + H2

Answer 2

The given sequence of transformations represents the conversion of compound C to HCOH. Let's break down each step:

1. C → CH₄: This represents the addition of four hydrogen atoms to compound C, resulting in methane (CH₄).

2. CH₄ → CH₃Br: In this step, one hydrogen atom is replaced by a bromine atom, leading to the formation of chloromethane (CH₃Br).

3. CH₃Br → CH₃OH: The bromine atom is substituted by a hydroxyl group (-OH), forming methanol (CH₃OH).

4. CH₃OH → HCOH: Finally, in this step, one hydrogen atom is removed from methanol, resulting in the formation of formaldehyde (HCOH), also known as methanal.

So, the overall transformation of compound C to HCOH involves a series of reactions: addition of hydrogen, substitution of bromine, and removal of a hydrogen atom.
