Help with all these please.

Slide appropriate reactants into the boxes to conduct the following synthetic transformation. You don't need to necessarily fill all the boxes, but if you don't use them all, fill from the top down. Unused boxes can be left Note: is probably best to work these on paper, the same way you would on a test. Then once you've got empty your answer, look for the chemicals in the bins your answer boaki or the chenicahs in way you would on a test. Then once you've got NaOCH3, CH30H PCC cyclopentanone H20, H+, extended heating H2Cr04 PhCOCH3 Bromoethane KCN PhCOCH2CH31-Bromopropane ethanal 3-pentanone BuLi (butyl lithium) PBr3 PPh3 propanal CHSCH2CO2CH 3Ph3 P-C(CH3)2 butanal(CH3)2CHCO2CH3 Nothing more needed
