The given compounds are to be arranged in the order of their decreasing formula mass. Concept introduction: Formula mass signifies the average mass of the compound. For any compound, the formula mass is the sum of the atomic masses of all the atoms in its chemical formula: Formula mass = ( # Atoms of 1st element in chemical formula × Atomic mass of 1st element ) + ( # Atoms of 2nd element in chemical formula × Atomic mass of 2nd element ) + ... Here, #atoms represents the number of atoms of the elements.

Interpretation Introduction

Interpretation:

The given compounds are to be arranged in the order of their decreasing formula mass.

Concept introduction:

Formula mass signifies the average mass of the compound.

For any compound, the formula mass is the sum of the atomic masses of all the atoms in its chemical formula:

Formula mass = (#Atoms of 1st element in chemical formula×Atomic mass of 1st element)+(#Atoms of 2nd element in chemical formula×Atomic mass of 2nd element)+... Here, #atoms represents the number of atoms of the elements.

Predict the major products of this organic reaction: HBr (1 equiv) cold ? Some important notes: • Draw the major product, or products, of this reaction in the drawing area below. • You can draw the products in any arrangement you like. • Pay careful attention to the reaction conditions, and only include the major products. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers. • Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
