There are (in total) 8 structural isomers of C5H11Br, from the 3 different 'pentanyl' hydrocarbon (-C5H11) isomers (n-pentane, iso-pentane and neo-pentane):

  • 3x in n-pentane: 1-, or 2-, or 3-Bromo-pentane
  • 4x in isopentane: 1-, or 2-, or 3-, or 4-Bromo-Methyl-butane
  • 1x in neopentane: 1-Bromo-diMethyl-propane

What is the difference between optical and structural isomers?

Structural isomers have the same molecular formula but different connectivity. Optical isomers have the same molecular formula but rotate plane polarized light. Optical isomers occur when chiral centers exist in a molecule giving rise to enantiomers. Enantiomers are molecules with non-superimposable mirror images. One enantiomer will rotate plane polarized light in the clockwise direction and the other will rotate it in the counterclockwise direction.




How can two compounds make from the same element be different?

Isomers are compounds that exist in different molecular arrangements of atoms of the same elements and having identical atomic weights. Although isomers of a compound contain the same atoms in their molecules, the atoms are arranged in a different molecular structure and the isomers may differ in their physical, chemical, and biological properties.

What is the molecular formula of ethonoic acid?

I believe you are asking about the formula for ethanoic acid rather than ethonoic acid, which doesn't exist. Ethanoic acid is the proper, systematic (IUPAC) name for acetic acid. The molecular formula is: HOOC-CH2CH3.

Is the number of atoms in a molecular formula always greater than a empirical?

No. A molecular formula can be the same as the empirical formula, such as CH4 (methane), because the two component atoms exist in a ratio that cannot be mathematically further broken down - one carbon to four hydrogens. In this case the molecular formula (the actual number of atoms per molecule), and the empirical formula (the simplest ratio of those numbers) is identical. On the other hand, ethane, C2H6 - two carbons to 6 hydrogens - has a molecular formula of C2H6 and a empirical formula of CH3, the ratio of 2 to 6 reduced to its simplest whole number form. Sooooooooooo, the molecular formula will always be equal to or greater than the empirical formula, and the empirical formula will always be equal to or less than the molecular formula. In other words (as if that wasn't enough), the molecular formula will never be less than the empirical formula and the empirical formula will never be greater than the molecular formula, but THE TWO CAN BE EQUAL.
