If 2 molecules of one reactant combine with 3 molecules of another to produce 5 molecules of a product, then what is the represe
zhenek [66]

Answer:- 2A+3B\rightarrow 5C

Explanations:- Let's say the first molecule is A and the second molecule is B and the product molecule is C.

From given information, 2 molecules of A react with 3 molecules of B to produce 5 molecules of C.

We write the reactants on left side and the product on right side and there is an arrow between them from reactants towards the products.

So, the reaction could be represented as:

2A+3B\rightarrow 5C

Functional group and bond hybridization of vanillin
lana66690 [7]

Vanillin is the common name for 4-hydroxy-3-methoxy-benzaldehyde.

See attached figure for the structure.

Vanillin have 3 functional groups:

1) aldehyde group:  R-HC=O, in which the carbon is double bonded to oxygen

2) phenolic hydroxide group: R-OH, were the hydroxyl group is bounded to a carbon from the benzene ring

3) ether group: R-O-R, were hydrogen is bounded through sigma bonds to carbons

Now for the hybridization we have:

The carbon atoms involved in the benzene ring and the red carbon atom (from the aldehyde group) have a <u>sp²</u> hybridization because they are involved in double bonds.

The carbon atom from the methoxy group (R-O-CH₃) and the blue oxygen's have a  <u>sp³</u>  hybridization because they are involved only in single bonds.
