WebCarbon atoms may thus form bonds to as many as four other atoms. For example, in methane (CH 4 _4 4 start subscript, 4, end subscript), carbon forms covalent bonds with four hydrogen atoms. Each bond corresponds to a pair of shared electrons (one from carbon and one from hydrogen), giving carbon the eight electrons it needs for a full … WebScience Chemistry Urea is easily dissolved in water, due in part to its ability to form hydrogen bonds. A urea molecule and four water molecules are represented in the diagram below. Identify which dashed lines between the molecules represent hydrogen bonding between urea and water. Select all that applies. U с a d b HO H b H H e O-H T …
