Answer:
The possible structures are shown in figure.
Explanation:
The seven isomers that could be formed from the given compound due to radical halogenation are shown in the figure.
We have mentioned only chlorine as group for showing just the chiral nature of the compound.
A chiral compound has a carbon with all the four groups different from each other.
There are three structures which are chiral (as shown).
W is the brominated product
X is the chlorinated product.
1) W reacts readily in water to form a chiral substitution product Y, C8H17OH.
Reaction of a single enantiomer of W produces a single enantiomer of Y as the only substitution product.: It means that the substitution is SN2 which is possible if the compund is not tertiary.
2) X likewise reacts readily in water though at a slower rate than W; a chiral substitution product Z, C8H17OH, is again formed. Unlike W, however, reaction of a single enantiomer of X produces Z that is nearly racemic.
It means that it will undergo SN1 reaction,. So the alkyl halide must be tertiary.
The possible structures are shown in figure.
Answer:
Q is 0.5 and K is 0.01, therefore K is less than Q.
the system will proceed in the reverse direction, thereby converting products into reactants. converting Nitric oxide to form oxygen and nitrogen.
Explanation:
Given,
N2 (g) + O2 (g) « 2 NO (g)
K = 0.01
heated temperature = 2000 ⁰C
N2 moles =0.4
O2 moles =0.1
2NO moles = 0.08
Volume of container = 1L
Q is the reaction quotient of the equilibrium equation. it is use to determined which direction the system will move to by comparing it with the K value.
Q can be calculated by multiplication of mass of reactant divide by mass of product
Q =
the mass of the chemicals are in mole, there is need to convert them to moles/litre
therefore,
for N₂ : 0.4 mole per 1L container = 0.4 mol/L = 0.4M
for O₂ : 0.1 mole per 1L container = 0.1 mol/L = 0.1M
for 2NO : 0.08mole per 1L container = 0.08 mol/L = 0.08M
Q = = (0.4*0.1)/0.08 = 0.5
finally, we are going to compare the value of Q with K
Note that:
if K>Q , the reaction will proceed forward, converting reactants into product.
if K<Q , the reaction will proceed backward, converting products into reactants.
if K=Q , the system of reaction is already in equilibrium.
since, Q is 0.5 and K is 0.01, therefore K is less than Q.
the system will proceed in the reverse direction, thereby converting products into reactants. converting Nitric oxide to form oxygen and nitrogen.
