If in a molecule the number of bond pairs are 2 and the number
of lone pair is 0, the possible predicted shape of the molecule
sa atin
a Linear
b Polygonal
CV-shape
d None of the above

i believe the answer is true.

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.
