Answer 1

CHY 7 • Number of valence electron un Chy is & • Lewis e Valence electron sphere of CH4. centructure neocon - Molecular Geometry can only be determined of we know about the hybridis atom. mo.of lone paw on Carbon=0 no. of Sigma bond pair 24 Total é paci= 0+4= 4 13p3) · Molecular Geomety for spa molecules in Tetrahedral. • Bond angle is 109.5 HINH o alue to difference in electronegativity of Carbon and Hydrogen CH is slightly polar in paturu. 14 Due to directional nature, all of the poles 4th cancels each other. Therefore, the resultant dishe momenti dipole moment is zero. The molecule in vector ! non polar. CS2 • Number of valence election us &. & Lewes structure S=C=S S&CES

180 Molecular Geometry no of lone pour on Carbono no. of Sigma bond pair = 2 Tolal e bain = 0+1 = 2 (3p) Molecular Geometry in lineas . :$_cas · Bond Angle = 180° • Bond polarity - polar. • S= = alue to equal and opposite depole moment vector, they cancel each other. Mnet = 0 Hence, Non-polar- # Has Hoogooh •Total valence electron=6 • Lewis structure no of lone pairs on Sulphur = 2 no of Sigma bond pairs 2 Total e paces = d+d=4 /sp3) Tetrahedral This is election pair Geometry - When molecule contain ilone pais of eleccion , uti molecular Geometry doesn't consider lone pairs in it. Molecular Geometry in Bent. Bond angle is 9200 Tetrahedral

→ The electronegativity difference betwen both atoms is less than 0.4. Hence bonds are non polar . If bonds are non-polar , werespective of its bent structure which allow the molecule to be polar , but due to non pou bond the moleute in non-polar. # soy? Ös-o Lewis structure . Valence election =8 ör3109.5 00 00 oal. no. of lone pair on S=0 no. of Syma bond pair = 4 Total és paius = 0+4 = 4 (sp3) • Molecular Geometry - Tetrahedoal. • Bong Bond Angle = 109.5" • Due to diffe" electronegativity as well as charge the bond is polar- • No cancellation of depole moment takes place due to veregular election cloud around Central atom. Hence molecule in polar.
