Web1 Answer Sorted by: 5 As Zhe pointed out in the comments, bolding both bonds looks 'weird', and if you look in textbooks or throughout the chemical literature, BINAP (and related systems) are commonly drawn with only the outer edge bolded (as shown on the left in the image below). WebSep 16, 2024 · Bonds between hydrogen and atoms in the same column of the periodic table decrease in strength as we go down the column. Thus an H–F bond is stronger than an H–I bond, H–C is stronger than H–Si, H–N is stronger than H–P, H–O is stronger than H–S, and so forth.
