How many of the following are meta orienting ? -underset(O)underset(|

1.	How many of the following are meta orienting ? -underset(O)underset(\|\|)C-OCH_3, -underset(O)underset(\|\|)C-OH, -underset(CH_3)underset(\|)overset(CH_3)overset(\|)C-CH_3, -N = O, -NO_2
Answer» SOLUTION :`-UNDERSET(O)underset(\|\|)C - OCH_3 , - underset(O)underset(\|\|)C - OH , NO_2`
