The shape around the oxygen atom in butan-2-ol is non linear. Predict the shape and angle of the C-O-H bond giving explanations
This bond can be described as having a non-linear or bent geometry, with a bond angle of approximately 104.5 degrees. It has this angle because the oxygen atom has 2 lone pairs and 2 bonding pairs of electrons around it. Lone pairs repel more than bonding pairs, so the angle is less than that of an atom with tetrahedral or pyramidal geometry.
