Write the Lewis dot structure of `CO` molecule .

Text Solution

Verified by Experts

Solution. Stop . Total number of valence electrons in ` CO = 4 + 6 = 10 (""_(6) C = 2, 4, ""_(6)C = 2, 4, ""_(8)O= 2, 6)`
Step 2. Skeletal structure is CO.
Step 3. Putting a single bond between C and O, i.e., one shared pair of electrons between C and O, and the
remaining 8 electrons as 3 long pairs on O to complete its octet and 1 lone pair on C, we have

Step 4. As in this structure , octet of C is not complete, multiple bonding is required between C and O . To ltbgt Complele the octet of C, triple bond is required between C and O . We should , therefore, shift two lone pairs on O
as shared pairs between C and O so that sctet of both C and O remains comlete. thus , the structure should be
