The number of covalent bonds in fluorine molecule is  

A)  2                                            

B)  3    

C)  1                                            

D)  5

Correct Answer: C

Solution :

                                The electronic configuration of fluorine atom is \[{{F}_{(9)}}1{{s}^{2}},\text{ }2{{s}^{2}}2{{p}^{5}}\] So, fluorine required only one electron to complete its octet. Thus, in the formation of fluorine molecule only one covalent bond is formed.
