Why B-Cl bond is polar? ​
aniked [119]

Answer:

The difference in the electronegativities of chlorine and boron is 3.0 - 2.0 = 1.0 ; the difference in between chlorine and carbon is 3.0 = 2.5 = 0.5 . Consequently, the B-Cl bond is more polar ; the chlorine atom asrries the partial negative charge because it has higher electronegativity .

The empirical formula of a hydrocarbon (compound that contains only C and H is found to be CH. laboratory procedures have found
gulaghasi [49]

Answer:

C₆H₆

Explanation:

Molar mass of the compound is 78g/mol

Unknown:

Molecular formula of the compound  = ?

Solution:

The empirical formula of the compound is CH.

Empirical formula is the simplest formula of a compound.

To solve this problem:

 Find the molar mass of CH;

       Molar mass = 12 + 1  = 13g/mol

Multiplication index  = \frac{78}{13}    = 6

So;

              (CH)₆  ;

 Therefore:

               C₆H₆
