A compound has the empirical formula CH and a molar mass of 78.11 g/mol . Find its molecular formula.
Reil [10]

Answer:

Molecular Formula = C6H6

Explanation:

Empirical Formular = CH

Molar Mass = 78.11

Molecular Formular = ?

The Formular relating these parameters is given as;

(Empirical Formula)n = Molecular Formular

where n = Number of moles

CH = 12.0107 + 1.00784 = 13.01854

(13.01854)n = 78.11

n = 78.11 / 13.01854

n = 5.9999 ≈ 6

Molecular Formula = C6H6

Describe the formation of a hydrogen bond and explain how it differs from a covalent or ionic bond
vlada-n [284]

Answers:

                  Hydrogen bond is formed when positive end of one molecule attracted negative end of other molecule. The concept is similar to magnetic attraction where opposite poles attract each other.

Explanation:

                   While understanding hydrogen bond, two terms are important, one is electronegativity (tendency of atoms to attract electrons towards itself) and other is dipole (separation of positive and negative charge in a molecule). Hydrogen bond is always formed between hydrogen atom and other atoms having electronegativity different than hydrogen.

Differ from Ionic and Covalent Bonds:

                        Hydrogen bond is weaker than ionic and covalent bond. Ionic and covalent bonds are intramolecular (within the molecule) whereas hydrogen bond is intermolecular (between molecules).

Example:

       Formation of hydrogen bonding in water.
