Carbon atoms are able to form long chains, while oxygen atoms cannot. what is a plausible reason for this difference?

a) carbon is much less electronegative than oxygen.

b) a carbon atom is very large compared to an oxygen atom.

c) chains of oxygen atoms can only be joined by single bonds.

d) the bond energy of o-o single bonds is too small for stable chains.

its first and third is your answer i did the qustion the fourth isnt right

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
