Question:

If in a compound leaving a group and corresponding beta hydrogen are not in anti periplanar position can alkene formation occur after beta-elimination??

Gaurav J.
Answer:

No, and Yes !! Actually, it depends upon molecule if there is a possibility that it will rotate and from conformer with beta hydrogen in anti periplanar position then it is possible. but if the molecule does not have such possibility due to hindered rotation no elimination occurs. Why anti peri planar ?? Yup this is the next question arises in our mind, so the answer is based on molecular orbital theory approach. According to it, anti bonding orbital of leaving group system(C-Lg) is in anti position, so it is easy for atom in the anti planar side to donate electrons in antibonding and get away with leaving the group(H-Lg).

Question:

Carbon has a possibility of giving carbon monoxide and carbon dioxide as well, but when we burn carbon (coal) we generally say that it gives poisonous Carbon monoxide. What about CO2??

Gaurav J.
Answer:

Yes, carbon has the potential of giving carbon dioxide and monoxide both as it burns, but what happens is there is a feasibility of reaction i.e. below around 427-degree celsius carbon dioxide production is more feasible but as we go to higher temperature carbon monoxide production is more feasible (based on delta G value). So if you look at Ellingham diagram this thing is more obvious since coal heating temperature is around 450-600 based on different types, so carbon monoxide is a unique product. Carbon monoxide is poisonous because of its strong tendency to bind with metal porphyrin system (Haemoglobin) than oxygen.

Question:

Water boils at 100-degree Celsius, and in "fever" our body temperature is around 100. Does it sounds possible??

Gaurav J.
Answer:

Ohhhhh first line of this statement is incorrect, before saying that water boils at 100-degree Celsius you have to specify what pressure condition are you talking about. At 1 atm water boils at 100-degree Celsius, if you increase the pressure then temperature also starts increasing. Now about the second part of the question, it is a silly thing actually fever is measured in Fahrenheit scale.
