Question

indicate the hybridization of the central atom in each molecule shown.

(first molecule: o=c=o with triple bonds? wait, the image shows a structure with o and c, and then another structure with be and f. then multiple choice options for each: sp³, sp, sp², sp³d², sp³d for the first; sp³, sp², sp, sp³d², sp³d for the second.)

Explanation:

For the first molecule (CO₂): The central C atom forms 2 double bonds (2 electron domains, no lone pairs). Hybridization matches the number of electron domains; 2 domains correspond to sp hybridization.
For the second molecule (BeF₂): The central Be atom forms 2 single bonds (2 electron domains, no lone pairs). 2 electron domains correspond to sp hybridization.

Answer:

First molecule (CO₂): sp
Second molecule (BeF₂): sp
