This structure has an incorrect number of bonds for nitrogen (too many hydrogens).<\/li>\n\n\n\n<li><strong>Option b<\/strong>: H-C-N-H. This structure places the lone pair of nitrogen appropriately, making it a valid choice.<\/li>\n\n\n\n<li><strong>Option c<\/strong>: H-C=N-H. This structure suggests a double bond between carbon and nitrogen, which isn&#8217;t correct since nitrogen can only form one bond with carbon here.<\/li>\n\n\n\n<li><strong>Option d<\/strong>: The image you provided seems to have some formatting issues and doesn\u2019t correspond to any valid structure.<\/li>\n<\/ul>\n\n\n\n<p>Thus, the correct structure for methylamine is <strong>Option b<\/strong>: <strong>H-C-N-H<\/strong>, where nitrogen has a lone pair and forms single bonds with both carbon and hydrogen.<\/p>\n\n\n\n<p>For the ionic formulas:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Potassium chloride (KCl)<\/strong>: Potassium (K) has a charge of +1, and chlorine (Cl) has a charge of -1, so the ionic formula is <strong>KCl<\/strong>.<\/li>\n\n\n\n<li><strong>Calcium hydroxide (Ca(OH)2)<\/strong>: Calcium (Ca) has a charge of +2, and hydroxide (OH) has a charge of -1, so we need two hydroxide ions to balance the charge, giving the formula <strong>Ca(OH)2<\/strong>.<\/li>\n\n\n\n<li><strong>Sodium sulfide (Na2S)<\/strong>: Sodium (Na) has a charge of +1, and sulfur (S) has a charge of -2. To balance the charges, we need two sodium ions, so the ionic formula is <strong>Na2S<\/strong>.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1376.jpeg\" alt=\"\" class=\"wp-image-264190\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Methylamine has a molecular formula of CH3N and the correct Lewis structure is the odor of rotten fish.
