Products are the substance that is obtained from the reactants as a final outcome of the chemical reaction and it is entered in right side of the chemical equation. In order to write a chemical equation four conventions are used and they are, Correct formulas of the reactants are written in left side of chemical equation. Correct formulas of products are written in right side of chemical equation. An arrow is placed between reactants and products which point towards the products. If two or more substances are present in reactant and product, plus sign is used to separate them. Balanced chemical equation is the one that has equal number of atoms of each element that is involved in the chemical reaction on both sides of the chemical equation. An unbalanced chemical equation can be balanced by adding coefficients to the equation. It is a number that is placed in left side of the chemical formula so that it changes the amount only and not the identity.

The number of hydrogens in an alkyne that has a main chain of 14carbons to which are attached a cyclobutyl ring, a benzene ring, an–OH group, and a Br is A. 34; B. 35; C. 36; D. 24; E. 43

Hello! I have a 500 Hz H-NMR for 1,5-bis-(4-methoxyphenyl)-penta-1,4-dien-3-one. I need to label the signals with the corresponding H's. Then, find out if the two alkenes are cis or trans by calculating the J values. I believe that I have the H-NMR labeled correctly, but not sure if I got the J values correct to determine if the two alkenes in the compound will make the compound cis or trans.
