Critical thinking problem: Acetylene torches, which are used in welding, burn at over 3200°C. Acetylene reacts with dioxygen to form two carbon dioxide molecules and also water. What are the hybridization orbitals of the carbons in acetylene?

What is the hybridization orbital for the carbon in carbon dioxide?

The oxygen in O2 has hybridization of sp2, while in H2O it is sp3. Since these are the same oxygen atoms, how could there be a change from one hybridization orbital to the other?

Consider the two electron arrangements for neutral atoms a and b. are atoms a and b the same element? a - 1s2, 2s2, 2p6, 3s1 b - 1s2, 2s2, 2p6, 5s1

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н,о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.
