Question

Determine the electron geometry and molecular geometry of the bolded atom Carbon in H₂ ${\color{Yellow} }$ $\large {\color{Yellow} }$ CO

a) eg=trigonal planar, eg=trigonal planar

b) eg=trigonal planar, mg=tetrahedral

c) eg= tetrahedral, mg=bent

d) eg=tetrahedral, mg= tetrahedral

e) eg=octahedral, mg= square planar

Answer 1

Ans: a

the electron geometry is the geometry which includes electron pairs on atom, whre as molecular geometry is the goemetry ehich excludes the electron pairs on atom while determining the geometry.

For H2CO

Carbon having outer electrons = 4

No. of electrons from H = 1 x 2 = 2

No. of electrons from oxygen= 2

No. of loan pairs = 4-(2+2) = -0

No. of bonds = 3

Hernce there is no difference between the electron geometry and molecular geometry

both are Trogonal plannar only
