The product(s) of a heated reaction of N,N-ethylmethylpentanamide with sodium hydroxide would be __________. View Available Hint
1 answer:
Answer:
sodium pentanoate and ethylmethylamine
Explanation:
The reaction of N,N-ethylmethylpentanamide with sodium hydroxide involves an amide and an inorganic hydroxide.
The CO-N bond is highly polar hence the -N(C2H5) (CH3) moiety is easily lost and replaced by the -ONa leading to the formation of sodium pentanoate.
The H^+ combines with -N(C2H5) (CH3) to yield ethylmethylamine

Answer: b). The B−A−B angles between neighboring B atoms are 90∘.
Explanation: The square planar geometry is the geometry in which the four groups are connected through an angle of 90∘ and all 5 atoms are in one plane.
It is not necessary for the molecule to have two non bonding pair of electrons on atom A but if it does have , then its parent geometry will be distorted octahedral. And if it doesn't have this non bonding pair of electrons then the geometry would be the square planar.
Thus the molecule has four electron domains about the central atom A if the parent geometry is square planar otherwise it would have 8 electron domain in distorted octahedral geometry.
The temperature : 332.75 K
<h3>Further explanation</h3>Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
volume of gas = 790 cm³ = 0.79 L
mol of gas at STP :
Use ideal gas :
P=726 mmHg=0.955 atm
V= 1000 cm³ = 1 L
