Help!!!

2. Using arrows, show how the sigma complex is formed when benzaldehyde reacts with a mixture of Br2 and FeBr3. Draw all important resonance structures of the sigma complex for each of the reaction shown below. If any form is unstable, place a box around it. A ring-activating group will lower the Ea of the rds (formation of the complex), will stabilize the complex and will direct the incoming group to ortho/para position. A ring-deactivating group will increase the Ea of the rds, will destabilize the complex and will direct the incoming group to meta position. Looking at the sigma complex can you comment if analdehyde group on the benzene ring willincrease/decrease (circle one) the Ea for formation of sigma complex and will prefer making ortho/para or meta (circle one) product
