Answer:
180 degrees
Step-by-step explanation:
The carbon in CO2 has 2 double bonds it forms with a adjacent oxygen atom on each side. After bonding, the carbon has no more lone pairs on its outer orbital. Hence the Carbon atome as 2 pi bonds. It is said to be sp hybridised and has a linear arrangement. The molecules are arranged in a straight line like so:
O=C=O
Hence, the angle between the C=O bonds is 180 degrees.
