Question In Woodward's 1952 synthesis of cholesterol, an elimination reaction was used to remove the C20 alcohol
substituent as shown below. The transformation is performed with acetic acid (hint: as opposed to a strong
base). Would you classify this as an E1 or E2 elimination?

Ola. E2
O b, E1​

Hi do not press the link please it will cause a virus on your phone.

question in what words 1952 synthesis of cholesterol and illumination reaction was used to remove the C20 alcohol substitute as shown below the transformation is performed with acidic acid hint as opposed to a strong base would you classify this as an E1 or an E2 elimination.

I would classify this as an E2 :)

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Answer is to avoid experimental error
