Question

(a) How many elements of unsaturation are implied by the molecular formula C₅H₅N? A) 0 B) 1 C) 2 D) 3 E) 4 (b) What two atomic orbitals or hybrid orbitals overlap to form the C-C sigma (s) bond in ethylene?A) C sp³ + C sp³B) C sp³ + C sp²C) C sp² + C sp²D) C sp³ + C pE) C sp² + C p

Answer 1

Answer:

(a) OPTION E=4

b) option E C sp² + C p

Explanation:

DEGREE OF UNSATURATION = C -H/2 -X/2 +N/2 +1

X IS HALOGENS

5-5/2+1/2+1=  4

b) Ethene comprises of two sp2-hybridized carbon atoms (bound to each other by sigma and two atoms each with hydrogen). The remaining unhybridized carbon p orbitals form a pi bond, giving ethene reactivity
