Compound a, c6h8, absorbed 3 equivalents of h2 on catalytic hydrogenation over a pd/c catalyst to give b (c6h14). on ozonolysis, compound a gave, among other things, a ketone which was identified as acetone. on treatment with nanh2 in nh3, followed by addition of iodomethane, compound a gave a new hydrocarbon, c (c7h10). draw the structure of compound c.

The structural formula of Compound C is CH₂(CH)₅CH₃.

Explanation:

Compound A is an alkene called Hexatriene, that is, it has three double bonds within its structure. Hydrogen atom is removed when compound A reacts with NaNH₂ in ammonia. Further reaction with iodomethane replaces the hydrogen atom with a methyl group from the iodomethane to form compound C.

Here is the step-wise mechanism:

CH₂(CH)₄CH₂ (With NaNH₂ in NH₃)> CH₂(CH)₄CH⁻ + H⁺

CH₂(CH)₄CH⁻ + CH₃I (Iodomethane) > CH₂(CH)₅CH₃ + I⁻

Compound C is called 1, 3, 5-Heptatriene.

i'm pretty sure it is letter c.) car

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
