Answer : 1. "nonpolar, with a symmetrical distribution of charge"
Explanation :
Answer: A) nonpolar, with a symmetrical distribution of charge Explanation: CF4 is tetrahedral. Since the four 'F' atoms have the same electronegativity values, there is no bias in electron distribution toward any one. Therefore, electron/charge distribution is symmetrical, which also means that the molecule is nonpolar. Hence, CF4 is nonpolar molecule with a symmetrical distribution of charge.
