Thank you for your good work.

For Q35: I believe your third isomer from the left is not cis-trans as the third carbon is attached to two of the same carboxylic side chains.

The other isomers can be found by moving one of the carboxylic group to the other carbons (this forms 2 other isomers)

Hey you explained that SIO2 wouldn’t react with Naoh under room temperature, however the sio2 (which came from sicl4 + water) reacts with Naoh ? Aren’t both sio2 under the same conditions? Please Explain
