I haven't slept in 2 days and am so exhausted. Please if anyone could help... I have class in 2 hours and it's 3am rn

Solution:-

Now

#1

Let's look at the EC of carbon(Z=6)

Now.

3 electrons are shared(1 with H_3C and 2 with N+)

Hence

Electron left unshared=4-3=1

#2

Lets look at EC of Nitrogen(N),Z=7

But

Its Cation i.e N+

Hence

Electron left unshared=4-3=1

#3

Lets look at EC of Oxygen(Z=8)

But it is anion hence 1electron required more which us bonded

Hence

Number of electrons left unshared=0
