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.

Answer : 1. "5 kmph"
Explanation :
Answer: A) 5 kmph Explanation: Let p be the speed of man in kmph According to the given data in the question, Distance travelled by bus in 10 min with 20 kmph == Distance travelled by man in 8 min with (20 + p) kmph in opposite direction => 20 x 10/60 = 8/60 (20 + p) => 200 = 160 + 8p => p = 40/8 = 5 kmph.
