Question

Assignment 2 Build models of all molecules shown in the table and investigate local geometry around each atom. 1) (24 pts) Fill in the blanks in the following table. 2) (8 pts) In Lewis structures, assign expected local geometries of atoms other than hydrogen (choices are tetrahedral, trigonal planar, linear, or bent). Structure #1 Structure #2 Molecular Formula Lewis Dot Structure нннн H-ċ---¢-H Condensed Structure Skeletal or Line structure CH151 - Chemistry in Your Life - Intro to Organic Chemistry -- V1.3

Answer 1

Solution i Molecular formula: Molecular formula of a Compound shows the exact No of atoms present, in that particular com peurd for example, éthane Holecular formella = Cato Lusis Dol structure: Lewis dot structure shows the "Bonding in compound and total shows total No. of bonds for example. Cha (HCC - H Condensed structure : Condensed structure shows only No. of atoms present. wilt does not show any bond. for example = propane - CH₂ CH₂ CH2 Skeletal or Line structure the compound shows by line structure in which the starting, joining and ending of line assumed as Carbon atom a ilich is tetravalad. In line a structure we does not show C&H atom we show only hetero atormy for example: prop are .
