Isomers Different compounds that have the same molecular formula

Isomers different compounds that have the same molecular formula... 

Constitutional isomers different compounds that have the same molecular formula, but differ in their connectivity (the sequence in which their atoms are bounded together).

ISOMERS DIFFERENT COMPOUNDS THAT HAVE THE SAME MOLECULAR FORMULA... 

In the introduction we noted that both Berzelius and Wohler were fascinated by the fact that two different compounds with different properties ammonium cyanate and urea pos sessed exactly the same molecular formula CH4N2O Berzelius had studied examples of similar phenomena earlier and invented the word isomer to describe different compounds that have the same molecular formula... 

Different compounds that have the same molecular formula are called isomers If they are different because their atoms are connected m a dif ferent order they are called constitutional isomers... 

Isomers are compounds that have the same molecular formulas but different structural formulas. Review the writing of the various structural isomers of alkanes. Make sure that each carbon atom has four bonds. 

A) Geometrical isomers are compounds that have the same molecular formula and the same groups bonded to one another but differ in the spatial arrangement of the groups. In the trans form of this compound, the two methyl groups are on opposite sides. 

One aspect of stereochemistry is stereoisomerism. Isomers, we recall, are different compounds that have the same molecular formula. The particular kind of isomers that are different from each other only in the way the atoms are oriented in space (but are like one another with respect to which atoms are joined to which other atoms) are called stereoisomers. 

Isomers are different compounds that have the same molecular formula they have the same number and kinds of atoms arranged differently. The term isomers comes from the Greek word meaning equal weights. Because their structures are dijferent, isomers have dijferent physical and chemical properties. Here we shall restrict our discussion of isomerism to that caused by different arrangements of ligands about central metal ions.
