The answer is (3).
CF4 is tetrahedral, so you can consider it to be kind of spherically balanced. 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.
Answer:
The outermost shell holds the so called valence electrons, therefore we have 8 electrons in that shell...
2s have 2 electrons and 2p hold 6 electrons 6+2=8
Answer:
c2h6
Explanation:
molecular weight=vapour density*2=2*15=30
molecular formula=empirical formula*n
n=molecular weight/empirical formula weight=30/15=2
so molecular formula2 * (ch3) alkane =c2h6
