What are the bond angles for a bent molecule that has four electron domains? a. 105
b. 116
c. 120
d. 109.5

The answer of the question is = d) 109.5

Explanation :

Notice that the tetrahedral arrangement of the four electron domains leads us to predict the trigonal-pyramidal molecular geometry. Because the trigonal-pyramidal molecular geometry is based on a tetrahedral electron-domain geometry, the ideal bond angles are 109.5°.
