possible?
A-1
B-2
C-3
D-4

Answer 1

answer is : A :1

Step-by-step explanation:

Double bonds are made of two bonding pairs of electrons (a sigma bond and pi bond). Triple bonds have three bonding pairs of electrons (a sigma bond and two pi bonds).

As the number of bonds between atoms increases, the length decreases, strength increases, and dissociation energy increases. This is because when...
