Toluene is an aromatic compound, generally it under goes electrophilic substitution reactions i.e. usually one of the hydrogen, is replaced by an electrophile. It increases the electron density at ortho and para position only not at meta. So electrophile attacks at ortho and para position.

∙ 14y agoInToluene methyl group attached to aromatic ring is electrons donor due to Hyper conjugation (Temporary bond breaking between carbon and hydrogen) so it is responsible to create negative charges at ortho and para positions and electrophile easily attacks at these positions.

Como se relaciona la ciencia y la tecnologia?
Se relacionan porque technologia necesita ciencias para evolucionar, como necesitamos experimentos para saber que lo que pensamos es verdad o por ejemplo coches, necesitabamos saber que cuando se vaporiza el gas le da poder al coche para moverse. Eso se encuentro con un experimento.
What are the two levels of of esd sensitivity?
According to 00-25-234, para. 7-4 its sensitive and super sensitive
Difference between engineering management and general management?
Engineering Managers are distinguished from other managers because they possess both the ability to apply engineering principles and skill in organizing and directing people and projects.

What are the examples of Ortho and para directing group and mata directing group?
Electrophilic Aromatic Substitution is an example of Ortho and para directing group and meta directing group.
Salicylic acid is ortho para directing group or meta directing group?
salicytic acid is a ortho para directing group ....however check up on that ...i am not completely certain .. Actually, it is a meta-directing group, because of the carboxylic acid functional that the salicylic acid contains. Hope that was helpful.
Why nitroso in nitrosobenzene deactivating yet ortho para directing?
NO-group acts exactly as halogens because of long pair on nitrogen. This pair stabilizes ortho-para intermediates.
What do you mean by the donor and acceptor ions?
Donor group are ortho-para directory groups that means increases in pai density of ortho para directory. Adaptor group meta directing groups that means increases in pai density of meta directing groups.
Why methyl attached to benzene is ortho-para director group?
This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
Although chlorine is an electron withdrawing group yet it is ortho - para directing in electrophilic aromatic substitution reactions?
In aromatic compound chlorine attached to the ring acts as the electrons donor group because the lone pair of chlorine becomes involved in process of resonance and is responsible to create the negative charge at ortho and para positions so acts as ortho-para director.
Why the electrophilic substitution reaction of haloarenes is oRtho and pera directing?
Because the +R effect of the haloarene, tends to oppose the -I effect, and hence the deactivation is lesser at the ortho and para positions, compared to any other position (like the meta position). So they tend to be o-p directing.
Ortho - hydroxyacetophenone vs para - hydroxyacetophenone polarity?
para is more polar than the ortho
Why 4-hydroxybenzoic acid is less acidic than 2-hydroxybenzoic acid?
4 hydroxybenzoic acid is para directing group whereas 2 is ortho directing group. thus at para, the two groups i.e. alcohol and carboxyl are far apart and thus dont show steric hinderance. therefore para directing group is a stable and as a result less acidic.
Why ortha para directors activate the benzene ring?
Ortho-para directing groups are those which can donate the electrons (lone pair or bonding pair by hyperconjugation) to benzene ring and create a negative charge on ortho and para positions by process of resonance so the attack of next incoming electrophile becomes easier as compare to unsubstituted benzene.
What is ortho meta and para in benzene?
ortho-para in benzene is meaningless these positions are for monosubstituted benzene. Meta is positions 3 and 5. Ortho is position 2 and 6 with relation to already attached group, para is 4 (opposite) to attached group.
What are the products of a toluene-sulfuric acid reaction?
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
