Answer:
See explanation and image attached
Explanation:
Alkenes undergo hydrogenation to give the corresponding alkanes. Where the structure of the original alkene is unknown, we can deduce the structure of the alkene from the structure of the products obtained when it undergoes various chemical reactions.
Now, the fact that we obtained 2-methylhexane upon hydrogenation and the two compounds had different heats of hydrogenation means that the two compounds were geometric isomers. The original compounds must have been cis-2-methyl-3-hexene and trans-2-methyl-3-hexene.
When reacted with HCl, the same compound C7H15Cl is formed because the stereo chemistry is removed.
However, we know that the trans isomer is more stable than the cis isomer hence the cis isomer always has a higher heat of hydrogenation than the trans isomer. Thus X is cis-2-methyl-3-hexene.
Answer:
of
is 0.0513
Explanation:
Solubility equilibrium of :
Solubility product of (
) is written as-
Where and
represents equilibrium concentration (in molarity) of
and
respectively.
Molar mass of = 183.48 g/mol
So, solubility of =
= 0.234M
1 mol of gives 1 mol of
and 2 moles of
upon dissociation.
so, = 0.234 M and
=
so,
