The structure of propenoic acid is shown here. indicate the type of hybridization for each numbered atom.

In Chemistry, hybridization is referred as steric number which is all about the regions of electron density that surrounds an atom. In this given problem, the structure of propenoic acid, here is the type of hybridization for each numbered atom:

Label 1, 2, 3 and 5 are all sp2

Label 4 is sp

 

 

A) the enthralling of formation for pure element in its standard state is always positivehope this : )

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
