Answer:
Methanol is more acidic than the alkyne and will be deprotonated instead.
Explanation:
of methanol is around 15 and
of terminal alkyne is around 26.
, where
is acid dissociation constant
So, higher the acidity of an acid, higher will its
value and thereby lower will be its
value.
So, methanol is certainly stronger acid than terminal alkyne.
Hence sodium amide preferably deprotonates methanol instead of terminal alkyne.
Hence, option (A) is correct.
Answer:
Equilibrium concentration of
is ![1.4\times 10^{-3}M](https://tex.z-dn.net/?f=1.4%5Ctimes%2010%5E%7B-3%7DM)
Explanation:
Construct an ICE table to calculate changes in concentration at equilibrium.
![CH_{3}COOH\rightleftharpoons CH_{3}COO^{-}+H^{+}](https://tex.z-dn.net/?f=CH_%7B3%7DCOOH%5Crightleftharpoons%20CH_%7B3%7DCOO%5E%7B-%7D%2BH%5E%7B%2B%7D)
I: 0.1 0 0
C: -x +x +x
E: 0.1-x x x
= ![K_{a}(CH_{3}COOH)](https://tex.z-dn.net/?f=K_%7Ba%7D%28CH_%7B3%7DCOOH%29)
(species inside third bracket represent equilibrium concentrations)
![\frac{x^{2}}{0.1-x}=1.85\times 10^{-5}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7B0.1-x%7D%3D1.85%5Ctimes%2010%5E%7B-5%7D)
or, ![x^{2}+(1.85\times 10^{-5})x-(1.85\times 10^{-6})=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B%281.85%5Ctimes%2010%5E%7B-5%7D%29x-%281.85%5Ctimes%2010%5E%7B-6%7D%29%3D0)
So,
M
or, ![x=1.4\times 10^{-3}M](https://tex.z-dn.net/?f=x%3D1.4%5Ctimes%2010%5E%7B-3%7DM)
So, equilibrium concentration of
=
=x=![1.4\times 10^{-3}M](https://tex.z-dn.net/?f=1.4%5Ctimes%2010%5E%7B-3%7DM)
Answer:
Double covalent bonds in carbon dioxide
Explanation:
The compound shown in the image is carbon dioxide. Carbon, the central atom in the molecule is bonded to two oxygen atoms. Carbon shares four electrons with each oxygen atom. The carbon atom is sp hybridized while the two oxygen atoms are sp2 hybridized.
The carbon atom is attached to each oxygen atom via a double covalent bond which implies the sharing of four electrons. Two electrons form the sigma bond while the other two electrons are shared in the pi bond thereby giving the double covalent bind indicated by the lines in the structure of the molecule.
Answer:
3150.5g
Explanation:
1 mole of nitric acid weighs 63.01g
so i did 63.01g times 50.0g which equals 3150.5g
g= Grams
