Question

Name the type of bonds that each arrow is pointing at. Electronegativity values are: H 2.2, C 2.5, N 3.04, 0 3.4 B C D A. H С N C OH CH HO сн. Bond that arrow A is pointing at: [Select] ionic bond polar covalent bond Bond that arrow B is pointing at: non-polar covalent bond hydrogen bond Bond that arrow C is pointing at: [Select] < Bond that arrow D is pointing at: [Select]

Answer 1

arrow a- HYDROGEN BOND

arrow b- POLAR COVALENT BBOND

arrow c- NON- POLAR COVALENT BOND

arrow d- IONIC BOND

REASONS FOR THE ABOVE ANSWERS-

a hydrogen bond involves two elements in which one is always hydrogen and other is the element which has appreciable electronegativity difference with hydrogen like oxygen, nitorgen , flourine. thus the arrow a includes the hydrogen atom, it is the hydrogen bond

there are two types of covalent bonds one is polar and other is non pola. the covalent bonds involve sharing of electrons, not the transfer, and carbon is the best example for covalent bond. now polar and non polar covalent is differentiated with the difference in electronegativity as it influences the polaroty of element which creates induced charge, in arrow 2 there is electronegativity difference, thus induced charge is there thus categorized into polar covalent bond, but in arrow 3- the elements are same which is carbon thus no electronegativity difference and categorized as non polar covalent bond

in arrow 4 it is ionic bond as there is large electronegativity difference thus complete transfer of electrons take place and ions are formed in aqueous solutions, thus it is ionic bond
