What is the characteristic angle between atoms in a linear molecule, such as carbon dioxide?
a) 360 degrees
b) 180 degrees
c) 120 degrees
d) 90 degrees
e) 100 degrees

A) 180 degrees

Explanation: According to VSEPR theory,No of electron pairs=

V= no of valence electrons of central atom (carbon) = 4

X= no of monovalent atoms = 0

C= cationic charge = 0

A= anionic charge = 0

No of electron pairs=

Thus as the electron pairs surrounding carbon is 2, the hybridization is . The shape of the molecule is linear and the bond angle is 180 degrees.

i think its 100

i hope this !
