A molecule contains four bonded pairs of electrons and zero lone pairs. What is the name of the molecular geometry?
1 answer:
Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.

Empirical formula: The formula consist of proportions of the elements which is present in the compound or the simplest whole number ratios of atoms.
Now, molecular formula is equal to the product of n (ratio) and empirical formula.
Molecular formula = (1)
molecular formula = (given)
Since, 6 is the smallest subscript in above molecular formula to get the simpler whole number of atoms. Therefore, divide all the subscripts i.e. number of carbon atoms (12), number of hydrogen atoms (24) and number of oxygen atoms (6) by 6.
empirical formula becomes
Thus, according to the formula (1)
Hence, empirical formula of given molecular formula is
