ESTER FORMATION, WHAT YOU MUST ALWAYS REMEMBER:
NOL DAC
Name alcohOL first, Draw ACid First!
so for 1: pentyl methanoate ; HCOOC5H11
2: butyl ethanoate; CH3COOC4H9
3: HEXYL BUTANOATE ; C3H7COOC6H13
4: try to do it youself. Remember : NOL DAC!

In each, Only H atoms are removed from Carboxylic acids, and OH from Alcohols. This forms water, while the remaining part is the ester. You always draw* the remaining acid part first and then the alcohol part. Try doing yourself and post your answers here, I'll check them
