Keisomeran struktur

Keisomeran kerangka mempunyai rumus molekul dan gugus fungsi yang sama tetapi berbeda rantai induknya.

Keisomeran

kerangka

Contoh

Keisomeran antara 1-butanol dengan 2- metil-propanol 1-butanol 2-metil-1- propanol C 4 H 1 0 O

C 4 H 1
0 O

Keisomeran struktur

Keisomeran gugus fungsi terjadi antar senyawa dengan rumus molekul sama tetapi berbeda gugus fungsinya.

Keisomeran

gugus fungsi

Terdapat tiga pasangan homolog yang mempunyai rumus umum yang sama, yaitu : ● (^) Alkanol dengan alkoksialkana (eter) mempunyai rumus umum CnH2n+2O ● (^) Alkana dengan alkanon mempunyai rumus umum CnH2nO ● (^) Asam alkanoat dengan alkil alkanoat mempunyai rumus umum CnH2nO 2

Contoh

1-butanol Dietil eter C 4 H 1 0 O

C 4 H 1
0 O

Keisomeran Ruang

Keisomeran optik

Keisomeran optik merupakan senyawa yang dapat memutar bidang cahaya terpolarisasi, karena mempunyai atom C kiral. C kiral adalah C yang mengikat 4 atom / gugus yang berbeda.

Contoh

butanol Untuk mencari jumlah isomer optik

C kirar

2 C kirar^ = 2^1 = 1
