Answer
41. (a)
As black represents carbon atom (C) and red represents oxygen atom (O) and each
red atom is bonded to the black atom, so this diagram represents a carbon atom
bonded to two oxygen atoms, so we can write
Molecular formula of compound= CO2
Name of the compound= Carbon dioxide
(b)
As blue represents nitrogen atom (N) and red represents oxygen atom (O) and each
red atom is bonded to the blue atom, so this diagram represents a nitrogen atom
bonded to two oxygen atoms, so we can write
Molecular formula of compound= NO2
Name of the compound= Nitrogen dioxide
Work Step by Step
1. Identify the atom corresponding to the color given in the problem.
2. Check the atoms which are bonded to each other.
3. Identify the molecule.
4. Write the formula and name of the compound.
