Answer:
The possible structures are ketone and aldehyde.
Explanation:
Number of double bonds of the given compound is calculated using the below formula.
=Number of double bonds
= Number of carbon atoms
= Number of hydrogen atoms
= Number of nitrogen atoms
The number of double bonds in the given formula -
The number of double bonds in the compound is one.
Therefore, probable structures is as follows.
(In attachment)
The structures I and III are ruled out from the probable structures because the signal in 13C-NMR appears at greater than 160 ppm.
alkene compounds I and II shows signal less than 140 ppm.
Hence, the probable structures III and IV are given as follows.
The carbonyl of structure I appear at 202 and ketone group of IV appears at 208 in 13C, which are greater than 160.
Hence, the molecular formula of the compound having possible structure in which the signal appears at greater than 160 ppm are shown aw follows.
Explanation:
Given temperatures are as follows.
Heat capacity for acetic acid =
Melting point of acetic acid =
Enthalpy of fusion for acetic acid = 11.73 kJ/mol
Number of moles of acetic acid =
= 2.564 mol
Now, conversion of solid acetic acid at to liquid acetic acid at
We know that,
=
= 30.075 kJ
Also, conversion of liquid acetic acid at to gas at
=
= 7252.1064 J
= 7.252 kJ (as 1 kJ = 1000 J)
Total heat energy required =
= 30.075 + 7.252
= 37.327 kJ
Thus, we can conclude that the amount of heat required is 37.327 kJ.
Answer:
These electrons then enter the non metal, causing it to form a negatively charged ion or anion which also has a stable electron configuration. ... When two atoms form a single covalent bond, each atom donates one electron to be shared between the two nuclei. When forming a bond, a carbon atom will 'share' one electron.
