H\u2082O<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In a liquid-liquid extraction or when two immiscible liquids are mixed, the <strong>relative densities<\/strong> of the liquids determine which layer will settle on the bottom and which will float on top. The <strong>denser liquid<\/strong> will form the <strong>bottom layer<\/strong>, while the <strong>less dense liquid<\/strong> will form the <strong>top layer<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#8217;s compare the densities of <strong>tert-butyl methyl ether (TBME)<\/strong> and <strong>water (H\u2082O)<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Density of tert-butyl methyl ether<\/strong> = <strong>0.74 g\/mL<\/strong><\/li>\n\n\n\n<li><strong>Density of water<\/strong> = <strong>1.00 g\/mL<\/strong> (at room temperature)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Because 0.74 g\/mL is <strong>less than<\/strong> 1.00 g\/mL, TBME is <strong>less dense<\/strong> than water. Therefore, <strong>TBME will float on top<\/strong>, and <strong>water will form the bottom layer<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This principle is commonly used in laboratory procedures such as <strong>liquid-liquid extraction<\/strong>, where it is critical to identify the aqueous (usually water-based) and organic (solvent-based) layers. Since TBME is an organic solvent and water is polar, they are <strong>immiscible<\/strong>\u2014meaning they do not mix and will separate into distinct layers. This rules out option <strong>d<\/strong>, which suggests miscibility.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why other options are incorrect:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. tert-butyl methyl ether<\/strong>: Incorrect. TBME has a lower density than water and thus will be the top layer, not the bottom.<\/li>\n\n\n\n<li><strong>c. The order is temperature dependent<\/strong>: Incorrect. Although density can slightly change with temperature, the difference in density between TBME and water is significant enough that normal laboratory temperature variations will not reverse their order.<\/li>\n\n\n\n<li><strong>d. These solvents are miscible; there are no layers<\/strong>: Incorrect. TBME and water are <strong>immiscible<\/strong>, so they will form two layers.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Since <strong>water is denser<\/strong>, it will form the <strong>bottom layer<\/strong>, and <strong>TBME will float on top<\/strong>. Understanding the densities of solvents is essential in laboratory separations and extractions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Correct answer: b.
