Question

c2h5+ lewis structure and formal charge

Answer 1

C₂H_5:( Lewis Structure):

C₂H₅ ( neutral no- overall charge) is a free radical.

Its lewis-dot structure will be two horizontal C atoms covalently bonded. One C atom will be single bonded to three H atoms . The other Catom will be bonded to two H atoms and have one electron unpaired.

FORMAL CAHRGE OF C₂H₅+:

The formal is a technique to identify which resonance structure is the most correct structure.The most correct lewis structure is the structure where the formal charges are evenly distributed throughout the molecule.The sum of all formal charges is equal to the total charge of the molecule.

formulae:

Formal charge = ve -NE - BE / 2

where VE = Valence electrons

   NE = non bonding electrons

BE = Bonding electron

  

Formal charge of 1st carbon is:

As the carbon belongs to 14 group in the periodic table the valence electrof varbon is 4

bonding electrons of carbon = 0

nonbonding electrons of 1^st carbon = 8

= 4-8-0/2

= 4-8-0

=-4-0

=-4

formal charge of 2nd carbon

valence electrons = 4

nonbonding electrons = 6

bonding electrons = 0

= 4 - 6 -0 /2

= - 2

finally the formal charge of carbon in C₂H₅ is   = -4 + ( -2 )

= - 6
